im going to paint my truck soon and i don;t like the trim so i removed it and am left with a bunch of holes. I heard the best way to take care of them is to weld them, then grind it smooth. Anyone done this, and can give me some tips? what kind of welder? Since theres so many holes in the front fenders from the trim, i'm just getting new fenders since the're only 33.75 a piece at a local place.
