I painted my old 89 honda crx with the door handles in... but then again I taped em off and it was only trim black paint and I didn't GAF. It was my 50 mpg getter and at 270k miles on all stock original motor I was averaging 47 combined.
Paint never peeled on that area. Idk about the flares. Looks good. Hope it lasts longer than the factory coats. Did you keep it the original color, flame red?
