What Grit Sandpaper for rubbing down between coats?

[Mikeyplum]

I'm currently in the process of respraying a few plastic parts off the car (wing mirrors, lower bumper grille, etc) in Satin Black.

I have rubbed down the parts with 600 grit wet + dry and applied 4 coats of Red Oxide Primer.

Onto the next stage of applying the Satin Black, I was thinking that 4 thin coats will be sufficient coverage. But what Grit wet + dry should I use in between coats? Will 1200 be to coarse? or should I go as far as 2000 grit?

Its my first attempt at respraying so most of it is done using common sense and some internet research.

After turning my utility room into a temporary spray booth and nailing a clothes hanger to the wall:

1200 should be fine.

I tend to use 1200 with water because the grit diminishes fairly quickly and you get a good finish. Less critical on satin I would have thought and 4 coats will cover anything.

So some 1200 grit and a bit of water should do the trick then! Happy Days!

Cheers guys!

1200 or even 1500. Fine.

you don't need to flat between coats unless you get dirt or crap in the paint
