Guide me through prep for spraying

[Faxo]

I've sprayed things before, but all I've done is fine sand, primer, colour, lacquer

I've always know you're meant to sand in between, but at what point and using what grade?

I attempted it in the past, after primer I think it was, but it just made marks the paint didn't fill!

So, what grade for initial sand, then can someone talk me through the process!

Thanks

tbh if your application is correct you shouldn't need to sand, other than to denib primer or clear, don't touch the basecoat. If you need to gloss up the clear 1500 and 2000 should do.

As above unless there is something seriously wrong with it, leave it alone.
