Help !! Rookie Needs Help!!!
Ok, so the first thing I have learned is that it is harder than it looks. I have a 71 F100 that I am "trying" to do some body work on. Mainly just repair or replace some of the panels and get it ready for paint. I am wanting to take all the paint (and rust) off the truck since it will be a different color. I bought a DA sander for this job which is working great for taking it all off. My prob. is that I keep on getting tiny half circle gooves or cut in my sheet metal. They cannot be felt by the touch, but you can see them. What is causing this? And is it a big deal? I tried different things such as not going so hard, going up and down, going in circle, changing the angle of the sander, and using a heavier grit paper. I was using 100 grit paper. any help or advice would be great. Thanks guys!
P.S. That guy on TRUCKS never made it look this hard.LOL

Once you sand the truck with 40 or 80 grit to remove all of the paint and such, you need to go back and sand it again with some 120 or 180. Shoot your underlayers and finally the build coat of primer. The paint guys can tell you how to finish up from there.

those marks are no big deal just get all the paint and rust off at this point, then go back over with 80 grit to help smooth them out. it will not come out complete and don;t put much effort into it. then you need to prime the truck with epoxy primer to protect the metal then you put a few coats of highbuild primer. after those steps are done there will be no marks left and the paint will be held great, the metal needs that tooth to hold the paint, you may even be able to leave the 100 grit scratch and be fine. i have never tried the 100 grit but ddi leave my last paint job with the 80 g swirl marks from the d/a. The highbuild primer is the one you wet sand for that baby butt smooth finish before base coating.
