Decals cracking

303 washes off in the rain, per a call to manufacturer regarding outside use. I do use the stuff on my tires because it doesn't affect the anti-oxidation compounds in the rubber.

As I posted somewhere some years ago, there is this stuff Marabu Classic Clearshield, which is a UV inhibitor for professional use on vinyl graphics. Not sold on Amazon etc., only from pro-suppliers like Lexjet. I had to use my company name to order, but was able to pay with credit card. It is $30 for a quart which is way more than you will ever need. You put it on with a brush.

DannyA, I am having the same issues with my class B, Did a search and came across the video on YouTube.

Seems to work.

Even with 303 it is a losing battle. It all starts with cheap low quality materials that builders use.

Nope, keep 303ing or waxing them and get the most outta them you can.

I HATE cheap vinyl decals on stuff exposed to alot of UV. With the RV industry, it is like an epidemic of planned obsolescence.
Some recommend scraping the decals right away before you get discoloration in the siding, but then your camper look like a FEMA trailer.
I've been slowly cutting back the "splash" looking decals on our old camper, keeps em from looking too raggedy. And you cant really tell since they are irregular shaped. If I actually had spare time, I'd scrape em all and either do some vinyl wrap, paint or get a new set of decals.

Mine mostly started to curl, and did the same , trimmed them back. It got to the point where you could actually see the border where they used to be. There is no secret they are eventually going to go bad, then its either replace them , or paint new ones .

There is no way I know of to hide where they were, the oxidation around them is nearly impossible to buff out. The shadows will show.

Not sure how long aged graphics might be to get off but on cars etc a hair dryer and a lot paitence and pulling and peeling possibly.
A Good RV Service Center may have dealt with this many times.Certainly the factory has. Call the factory and try to speak to a tech in their service department...unless you don't care and are going to trade it etc.If i could I would paint on new graphic of your design or copy the decals,if the pint or fibergalls finish is still good.

That is what I was looking for some type of finish/sealer to keep them from starting to peel. If anyone knows a product give me a name please.

Seven to ten years is about it for graphics no matter what you do.

My rigs 30 yrs old and with a few minor exception the graphics are OK. I used an acrylic finish. How long they last may depend on how they are protected, where you live (ie how much exposure to baking sun).

Seven to ten years is about it for graphics no matter what you do.

Apply 303 every 6 weeks on entire exterior of trailer.
It only takes me 30 minutes on a 30ft trailer using a car wash mop.

Sound a little excessive? Perhaps but it works.

No peel yet, just a few cracks.

If you are lucky, they may not peel. My sun side, when parked has cracked, but I still use 303 on them, couple times a year, with no peel yet.
