Finishing Paint - HELP!

[Joe3334]

Actually, just a quick question, given i've over sanded for a solid paint (1200 light sand), will the SCA primer filler still be ok to spray straight on rather than go back to a light sand of say 400??

I personally sand in between coats of paint with 600, it's just on the verge of being too smooth for painting but also rough enough to actually remove material/paint. Your prep work makes up for about 80% of the end result and the actual process of painting, wet sanding and polishing is the remaining 20%. Adding the clear is kind of the same as adding colour or applying primer, it's just that you'll need waaaaaay more coats of clear then you'll need of colour and primer. There's some extra things you'll need to do after applying the clear but I won't elaborate on that just yet.

Also, I'd recommend sanding again with a lower grit e.g 400 so that the paint really sticks, 1200 is a bit too smooth.
