This is the drivers side front fender. The color saturation of this photo has been modified so you can better see the difference between these three repairs. As you know this fender had fire damage several years ago and because of that this fender gets extra attention. When I saw this fender had blemishes I decided to grind into the fiberglass to make sure we didn't have bigger problems. The repair in the middle had good fiberglass but the other two had issues. You can see the difference in texture and color of the shavings. White is right.
Both bad areas were ground until good fiberglass was exposed. The bad spots were each about the size and thickness of a silver dollar. All three areas were masked off then fresh fiberglass and resin was applied.
