Re-Paint ??... Pro's Chime In....

If its not in too bad of shape,like not cracking or peeling everywhere,you can scuff it down,or sand it using 320 on a DA Sander.If there is small dings,you can use polyester glaze putty,but you have to use the thicker filler for larger dents.I like using Evercoats glaze putty and their Gold Filler,Bondo brand is ok,but omg its like sanding concrete.=\Etch the bare metal spots(you can buy a rattle can of etch primer for small areas)Prime the body work(use good catalyzed primer,not the rattle can stuff,it will shrink and you will end up with swells)block sand the bodywork.I do like to seal them just so the car is one whole color,light sealer for light colors,dark sealer for dark colors.(ever try to paint something black yellow?Sometimes its a PITA to cover,lol)A nice base/clear paint job will do.I like to stick with 1 system,for example,Dupont base,with Dupont clear,Dupont hardener,reducer,etc,but you can use a more affordable universal clear that will work on most base coats.Just go to your local auto paint store and shop around for a good paint system =)
