sanding

sup fellas i got tierd of hand sanding my car so i got one of those orbitol sanders and i wanted to ask what grit sand paper should i get? cuz im hearing the wrong paper can mess up the metal?

you won't mees up the metal... the plastic, yes. use 320-400 grit paper for regular sanding. 80 grit if you want to strip down till the bare metal.

After done sanding.... get 600-800 grit and sand some more. go over everything with 600-800 to smooth it out.

sand plastic parts by hand only... or very very lightly with sander.
