What Is This "Invisible Bra"?

Over ten years ago, 3M and maybe other companies came out with their “Invisible Bra” for automobiles and specifically for RV’s.

It was hailed as the final and perfect solution for keeping bugs and small scratches and dents from rocks off of your RV front end. And honestly, it worked! Everyone in the RV industry jumped on the bandwagon to provide this product to RV owners.

The bra was a special clear plastic, in sheet form, that could be cut and glued to the front end of your RV. Since it was clear, it allowed your RV paint job to show through, and furthermore, it was also guaranteed to not block any UV rays from the sun, so the paint under the plastic would “age” and “fade” at the same rate as the paint that was not under the plastic. So, it was argued, you could remove it later and your paint job would be unchanged and you wouldn’t be able to tell if it was ever on your RV.

Then you add the fact that it was guaranteed to meet these specifications for ten years, and you had a product everyone wanted on their RV. So, for the next five years or more, this invisible bra was placed on the majority of RV's sold.

It was great. You had your front end protected, and your paint job looked great, it was invisible, right?

That Ugly Not-So-Invisible Bra Can Cost You

If your RV has an invisible bra that is torn, tattered and stained, its trade-in or sale price can be reduced dramatically.

Bugs Drove People to Consider Invisible Bras

Bugs, from tiny mosquitoes to large strange things that seem to have wingspans that block out the sun, splatter onto your RV's front end.

Some are just individual insects that have lost their way, I guess, while others travel in swarms that are so thick, when you drive through them it sounds like you have run into a sandstorm.

If your RV front end isn't protected, it can soon become a pock-marked surface with dried up stains everywhere.

Of course it never helps when your RV front end is a flat surface with absolutely no aerodynamics to help some of these things slip off to the side and miss your front end.

People used different things to get the front of their RV and their windshield clean after a long day on the road: soaps, detergents, scouring rags, brushes and more.

Many RV owners installed a black vinyl "bra," custom designed for the front end of a specific model of RV. It fit like a glove and was (supposedly) easier to clean than the front end. It usually fit and looked good, but it did distract from your fancy RV paint job.

Many RV owners were frustrated with this bug-and-rock problem and jumped on the opportunity to buy an easy-to-clean, stylish addition to an RV: the new Invisible Bra.

An Invisible BRA Does Not Eliminate Bugs

Keep in mind that an Invisible Bra does NOT prevent bugs on your RV; it just collects them on an easier-to-clean surface.

How the Invisible Bra Was Installed

The Invisible Bra concept was a simple one.

You place some clear plastic onto the front end of an automobile or RV and it took 99% of the abuse a bare front end would have taken from bugs, sand and small rocks. The manufacturer had a disclaimer in case you were hit by a rock that was large enough to cut through their thin layer of plastic.

The application process was a relatively simple one.

  • First you cut the clear plastic to roughly fit the area of the vehicle's front end.
  • Second, you washed, cleaned and then wet down the section of the body you wanted to protect with the plastic.
  • Third you wet down the back side of the plastic which had a thin coating of a glue that the water activated.
  • For the final step, you placed the wet plastic onto a wet RV front end.
  • Once it was roughly in place, you just used a squeegee to push the water from under the plastic, making sure to eliminate any bubbles that might show up as you worked the plastic with the squeegee.
  • And finally, the plastic was elastic to a degree, so it could be “stretched and shaped” as you used your squeegee.

Then you just sat back and waited for the glue to dry. Once the glue was dry, you had a piece of plastic that was a perfect fit over your RV paint job, that would be there for years.

Or so they thought.

Time and the Invisible Bra on an RV

But, after a few years, people started complaining. Their Invisible Bra had started to be, well, visible.

Remember, the bra didn’t get rid of bugs, and you had to clean them off, yourself. The cleaning guidelines said to “use your regular RV cleaning detergents."

Of course, every RV owner used whatever cleaning substance they liked to get rid of the bugs, generally the stronger the better. And, for those pesky stubborn areas, they often used tools (rags and brushes) that scratched the plastic layer of the bra and often went all the way through it.

Well, over time, these scratches allowed small amounts of water and also mold spores, it seems, to work their way into the scratches and onto the paint itself. This trapped mold built up to the point that the typical RV front end looked like it was covered with brown “rust” under the once-clear plastic layer.

The manufacturer was safe, of course, because we RV owners had used things to clean those dead bugs off of our mont ends that were definitely NOT on any approved list of cleaners.

So, we all just kept on running in our RV's with their-now ugly front ends. And OK, it looked bad, but the bra was still protecting that front-end paint job, and when you pulled into a campground, everyone knew what the situation was; just another bad Invisible Bra.

Putting a Bra onto an RV

What Went Wrong With This Wonder Product?

Over time, these accumulated scratches and small holes destroyed the look of the Invisible Bra.

I guess, what was never considered is just how desperate an RV owner might be to get rid of dead bugs.

Harsh chemicals, brushes and other tools left scratches in the plastic coating, and sand and gravel, flying at high speeds when kicked up from the road, put thousands of very small pinholes in the plastic in addition to the scratches.

The final catastrophe for the RV owner who had used this Invisible Bra was the growth of mold. These pinholes and scratches allowed water to enter under the edges of the plastic, and the water became a perfect breeding ground for mold to grow, and eventually, to die.

And, of course, the dead mold turned an ugly dark brown. So, the RV owner watched helplessly as his beautiful front end slowly turned into a collection of brown lines and spots.

How Do You Get Rid of This Plastic Covering?

As ugly as a mold-infested plastic “Invisible Bra” might make your front end look, the paint job under that bra is invariably in great shape, near-perfect condition, in fact.

So, the goal of every RV owner is to get this ugly plastic off of the RV without harming the underlying paint job.

To get the bra off without harming the paint, the owner needs to deal with two problems: the plastic itself and then the glue holding it to the paint. Each layer requires a different approach.

Warning #1 - The plastic itself generally has so many scratches, usually cut all of the way through the plastic, that attempts to just peel it off will fail. As you peel it, it separates every 1/8-inch or so, and you end up removing thousands of small pieces of the plastic because it will just will not peel off in larger pieces.

Warning #2 - If you try to use harsh chemicals to remove the plastic, it turns into soft sticky balls of plastic that will harden quickly, if left on the body. These can take days to dry enough for you to actually remove them. Furthermore, most of the chemicals that can remove the plastic, can also damage your paint job, so you have to be careful selecting and using chemicals.

What Are Your Options?

There are only a few "best" methods of removing an Invisible Bra from the front end of an RV.

Go to a Paint Shop

You can go to a good automotive paint shop that is comfortable with painting RV's.

They will remove not only the plastic and glue, but the paint itself, and then simply repaint your RV front end. Your RV ends up looking great but you will have shelled out several thousand dollars for your new and nice-looking front end.

Use a Heat Gun

I know someone who used a hair dryer. The heat slowly weakens the glue under the plastic and allows you to actually peel away decent-size strips of the plastic. But, he did admit that it was a very slow process.

You have to keep the hair dryer far enough away from the paint so you don’t harm the paint itself, while at the same time stay close enough to weaken the bond of the glue.

This is a tricky way to remove the plastic, but I understand that a steady hand can do it properly.

Of course, you then have to get rid if the residual glue left behind.

Plastic Scrapers

Probably the most people I have heard from told me they used paint scrapers.

The scrapers were not made of metal but rather they were cheap one-piece plastic scrapers. They said they had “used a lot” of them to get the job done.

You see, the edge of the plastic scraper has to be straight and beveled to a sharp edge, or at least what passes for sharp when something is made of plastic.

The scraper had to be sharp enough and firm enough that it could be worked under the edge of the plastic bra, while at the same time not scratching the underlying paint.

The areas with fewer scratches peel more easily. The process is labor intensive and takes a lot of time. Most of the people who used scrapers would pick a small area at a time and not rush through getting rid of their Invisible Bra.

What Did I Do?

First I read a lot of labels on paint removers, adhesive removers, paint cleaners and other chemicals that I found on the shelves of Home Depot.

When I went home to look up the ingredients in these cleaners, the possible health effects from some of them scared me as much much as the potential environmental hazards. So, I eliminated the possibility of using most of the chemicals I did find.

I decided I wasn’t going to use a heat gun or hair dryer and create a new problem (accidentally damaging my paint) while trying to solve another, so that option was eliminated.

And honestly I simply couldn’t afford to take my RV to a paint shop and spend the kind of money the other guys told me they had spent getting their front ends redone.

Scrapers Plus Goo Gone

So, I ended up using paint scrapers. But I went one step further. On Amazon I found some scrapers, made like the ones which use old-fashioned two-sided razor-blades for scraping labels and stickers off of a windshield, or paint from a newly painted window frame and glass.

But these were different, The holder was the same design but it was made of plastic, and the vendor also sold packages of two-edged blades (like razor blades) made of plastic.

They were priced right and I ordered a few of them to try out. They worked great for me. When you take your time, you can use these to relatively easily scrape off pieces of the plastic bra,

After that, I use a not-very-powerful, but safe, cleanser called Goo-Gone.

I coat the newly exposed glue-covered areas with the Goo-Gone, and then wait a few minutes for it to soak in. It softens the glue enough that I can then scrape it from the surface of the paint.

Oh, it’s still a slow, manual process and it seems to take forever, but, as I said, it’s cheap and it works. So, my recommendation is to use more elbow grease, spend less money, and get rid of that darn not-so-invisible bra on the front of your RV.

I'm nearly 2/3 done, and my RV will soon have its original front end paint showing all over. Then with just a good washing with soapy water, followed by a good hand wax, it will look like new.

        Charles Ketchum - You're right it is a tedious process. But the main thing is to not damage that paint/clearcoat surface of your RV. When I did mine, I ended up leaving a lot of little "gobs" of black-looking glue, but I waited a couple of weeks and then I went back and then they came off much easier.

        Good Luck,

        Don

        I've just started this process on my '05 Newmar. It really takes patience. I'm using the plastic scrapers I purchased from Home Depot's paint department. It takes a lot of time to sharpen the stupid things.

        I will be ordering the razor blades you found this afternoon. I don't need a heat gun here in Laughlin, NV as mother nature is providing heat in the form of 103-108* heat daily.

        The Goo Gone isn't working as well as you described but I wasn't able to get as much adhesive residue off because of the crappy scrapers I am using. I'm glad you posted this and I'm glad I found it.

        Thanks

        BlossumSB - Actually, the whole "invisible Bra" fad started with automobiles, and honestly they work better on a cars front end, just because an automobile isn't on the road as much as an RV, and an automobiles front end is streamlined and rejects most bugs anyway, unlike the big square, flat front end of an RV.

        But, they can go bat also!

        Thanks for the read and comment,

        Old Poolman- Interesting idea to use dryer sheets. As I think about it, I have seen these things used for a number of unusual applications. For instance, one old-timer told me they put them under their RV jacks because insect did not like the scent, so it kept ants and such away from your crawling into your RV.

        I think I'm going to have to read another label now, LOL!

        Thanks for the read and the idea.

        It's not only RVs that collect bugs - my car's quite good at it, too. I don't think they've invented an invisible bra for cars yet. Perhaps it would stop the air from cooling the radiator, and that wouldn't be so good.

        So this device which was supposed to solve (or lessen) the bug problem created its own problem. Glad you are able to fix that problem. Cheers to your persistence!

        Good Morning Don. I'm sure this hub and the video will be helpful to many who have been trying to do this very nasty job.

        I'm not an RV guy, at least not yet, but do fight the bug splatter problem on my truck and my wife's car. I tried all different kinds of off-the-shelf bug remover products, and none of them worked.

        One day I was surfing the web and found a YouTube video on bug removal and I decided to give it a try.

        The method is to take a spray type bottle, put a dryer sheet in the bottle and add just enough water to cover the dryer sheet. Let it soak for awhile and then dampen a second dryer sheet to use as a wiping cloth. Then spray a few of the bug splatters and let it soak for a couple minutes and wipe it off with the wiping sheet.

        I couldn't believe how quickly the bugs came off and there was no scratches in the paint or paint damage that I can see. I always wash the whole vehicle when I finish but this method doesn't seem to leave any residue behind even without washing.

        Just thought I would throw this out there in case it might help a few people who fight the bug problem.
