Thanks, Marq. After doing the bodywork on this fender, I've wet sanded the primer with 400g, all the fuzzies are gone. So I will go over it with the liquid primer, I guess I should be ok with that. I did sand the hood down to bare metal to clean up a lot of surface rust, and spray primered that. Haven't sanded it yet, but will before I go any further with it. The rest of the truck is just filling in emblem holes and removing the trim studs, so I may just use the spray primer for these areas and cover the whole thing with the roll-on before paint. Thanks for the help.
