Jeff78rr posted:It looks lIke the issue is the underlying surface wasn’t gloss. Also I would trim that decal film as close as possible to the lettering. You can likely remove those with water, redo and re set.
I have always sprayed a car or loco with gloss (I like ScaleCoat II) letting it dry overnight. Then applying the decals with a decal setting solution. Once the decal is down and completely dry (over night) then use a clear flat.
