Please don't laugh.
Don't know how extensive your scratches are. But, the first day we brought our rig home, as I backed her into her berth, I got into a pomegranate tree. Put a nasty scratch/tear in a decal. SWMBO lost her usual good humor.
Spent much time on phone and the net looking for a replacement decal. No luck. Finally went to a local print shop that does vehicle decals, advertising shrink wraps, etc. They looked over the problem, decided they couldn't get a color match, but did have a suggestion. The way they repair scratches/tears in their products.
Fingernail polish. Gazillions of colors. Acrylic enamel. Fills in scratches. Can be buffed out level to surrounding paint or decal.
Worked for us for a couple of years until we got tired of wrestling with fading decals, and removed them all and painted them back on.
