Ok, so I have done a tonne of renovations to my 1990 Starcraft Starstream. I am about to get into the exterior and my pinstripes and decals look like hell. I tried a heat gun, a wire wheel on a drill, a sander, etc. Each failed. The heat gun and wire wheel in combination worked well, but sloooowwww and its spread the color of the decal. Anyway, I heard that if you spray an oven cleaner on the decals and let it sit for 15 minutes, they pretty much come right off! I am about to try a small area tomorrow morning (fingers crossed) but was wondering if anyone has tried this, or has another option that works!! Remember.............these are 23 yr old flaking, but still very stubborn decals that I need off for painting.
