whats the best way to do the final sanddown on the lacquer coat. i know that u sand it down using 1200/1500/2000+ grit wet and dry and do it using plenty of water but is there any other tips to get the finish looking smooth and glass like? i.e pressure required, sanding down corners etc. i dont wanna rub it down to the point of going through to the primer but dont want it to look shoddy either.
