What grit of sand paper should I be using to sand the engine cover and fuse box cover etc.? The autozone guy told me 400 so I bought 400 grit but im not sure I got metalcast paint too and it says use 400 grit but it doesn't tell me what to use for plastic. :confused:

use a good cleaner, a plastic prep and an adhesion promoter.
Don't sand the plastic, *lightly* scuff it to just give it enough tooth to bite into.

Do a VERY light initial coat let it flash off, then spray 2-3 more med-wet coats

when i did my cover i just brought it into the shower and did a really good rinse and a little bit if simple green to clean it off. then let it dry and then painted it. no primer no sanding no scuffing. looks good to me
