Decal Removal & Painting Aluminum on Fleetwood Prowler

My 2000 Prowler has terrible paint and decals. As a capable do-it-yourselfer I decided to start by repainting just the front end using spray cans.

I used a heat gun to remove the decal. It was sun damaged and came off in small pieces.

I stripped it down to the bare aluminum and carefully applied Rustoleum per the directions. Looked great for a few months then started to peel. Did it again using a different self-etching aluminum primer and different paint. A year later it's peeling again. I've painted some of the worst bare spots with Krylon 'Fusion' and so far so good. I figured if Krylon sticks to plastic maybe it'll stick to aluminum.

I attended the FMCA Rally in Indio last January. I looked at examples of paint quality and got estimates from four vendors.
I just had the decals removed and a partial body paint (covering all shadows of decals) on my RV. Work was done by Collision Clinic in Palm Desert, Removing decals was a problem as they come in different mil thicknesses and can not all be pulled off, especially if fractured by the suns rays. To remove the difficult decals they used a special tool just for that purpose. It looked like a stack of silicone pancakes placed on a rod and put on a drill. It quickly removed the decals without damage to the fiberglass surface. Painting is an Art and not all paint is the same. I recommend a professional painter who guarantees his work and products.

Time and Patience are required to do a good job .
Pick a hot day .
Use the hair dryer or heat gun .
Peel very slowly .
Figure a half day to remove them all .
Your option , there are lots of colored swooshes and other designs available online to install after you have taken the brand name stuff off .
You can often match the decal on your tow rig to your trailer .
If you spend a month at Palm Springs and hit the RV shows in the winter there are several vendors who have a display .
The swooshes I had applied in 2004? show no deterioration or peeling .
I paid to have a pro do the install .
The removal better fit my skill level .
Besides what else am I gonna do while hanging out at the RV Resort ?

Cant help with the painting part but using a heat gun about 8~10" away from the decal will make it lift easily and leave no residue behind.
