Because this fender is so much better, I'm just patching the defects. Notice the square tube brace to try and keep the fender from changing shape (I learned from the last one). Two spots patched (silver paint), the biggie in the corner next. I hammered the rust away with a needle-scaler attachment on my air hammer. All the rust came out of everywhere, and opened some holes. I'm trying to do -something- every day instead of saving it all for a time-spartan weekend.
