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.coaster wrote: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).sydduckett wrote: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....GBCS wrote:2000 is too fine for a mechanical key, I would use 800 between clear coats.
will hopfully be doing this tomorrow
