polishing lacquer

[GBCS]

2000 is too fine for a mechanical key, I would use 800 between clear coats.

Hold up i wasnt going to flat off between coats, do i need to do this? thats going to be a bit of a pain in the ar*e if i do. will mean the process taking a lot longer as dont have acres of space to do all the parts at once. also means cleaning the gun out after each coat.....had a near miss in the summer waiting on some lacquer in the gun and it started going off. Whole gun had to be stripped and cleaned half a dozen times....

Don't worry Sid, he means to use 800 to flat off before putting the additional coats on. No flatting required between coats as you are applying onto a wet surface (well not cured anyway).

Sorry if that wasn't clear !, Coaster is of course right, if you are spraying successive coats within the "open window" specified by the paint manufacturer, you will get a chemical key. Once you go beyond that window, or you are recoating old paint, you need to scuff for a mechanical key.
