Decal removal FAIL and HELP!

Hey all,


Got a 2007 Coachman Mirada 350DS.


So after watching a gazillion YouTube videos I decided to try the heat gun removal process. So heated up end of one of my decal and tried to peel it up and this is what happened.







Anyone know why? Did I get it too hot? Any thoughts on what I need to do to seal up this hole?


I ditched the heat gun and started on a decal on the side of the RV that's been sitting in the sun all morning, and I'm able to peel it off but if very small pieces using a plastic razor. This is gonna take awhile.


I'm also trying the eraser wheel, but that also slow going too.


I expected this to be a slow process but WOW!!



Thanks!


Mike

Looks like gun was too hot and blistered the coating. When I use a heat gun, I start low and slowly increase to try to use the minimum heat on a sensitive application.

And the 3M wheel isn't working either?

Yeah I've ditched the gun, obviously I can't be trusted with it hahahaha

the 3M wheel works great on other decals (usually different colored ones) but this one is stubborn and seem really really baked in.

For this one I ordered

And will try it on the baked in decal.

I used a Whizzy Wheel for my baked on front decals. I also had to buy a higher speed drill. Oh darn
Whizzy Wheel worked better than anything, including harsh chemicals. That chemical you are looking at has a lot of warnings for plastics and untreated fiberglass.
My baked on graphics came off easily with the wheel. The adhesive took a little longer, small amounts of Goo Be Gone, WD40, and a plastic razor blade worked.

I got a Whizzy Wheel also and using it too.... I used it at high rpms but it made yellow burn stains in some spots on the fiberglass. I'm going to try again at lower rpms.

This guy posted a video using the graphixoff stuff



looked easy enough to use, but I'll try it on small test area first

Ah. Yes, at first I also had a few yellow spots when the wheel was new. Later I didn't get any. My yellowed spots buffed out with a gel coat deoxidizer/cleaner from Maguiars.

This is the spot I'm talking about. Is this what you had too?

Unless you are planning to replace the decals as they were, I would not remove them from an older trailer. The effects of the sun will be noticeable and possibly hard to correct.

I has some decals once that turned ugly, I just used a blow dryer to warm them to get them off, a heat gun is too hot for that job.
