Of course I started with the two front fenders about three years ago? I sanded them with 100 Grit to get the paint off and then sanded the metal with 220 on a Harbor Freight Disc Sander. That's what I did today also. Then I finish up with some 400 wet and dry going from front to back in One Direction. Then I just use some rattle can clear. remember my car stays inside a warm or fairly warm garage all winter and just sunny days in the summer and never in the rain. I usually clean in between with mineral spirits. In the last year I've done the doors the trunk lid in the hood with the hole in it. 1 Fender is showing some very find surface rust in one little area which I might wet and dry over again and respray.
