more often than not, I do ok with dust.. a hood is obviously the big test.. which i will be spraying mine next week.. I've sprayed in enough sh*tholes over the yrs to know a few tricks.... my biggest complaint is the pervasiveness of the overspray.. i'm really not set up with full blown filters and good fans at the moment, so it takes a while to clear with just the 1 small fan going..
they didn't come out perfect... there's one small dent in the door I missed, plus some sandscratches in the fender and a bit of dust and orangepeel here and there... but like I said, at the end, I'll block out the whole cab, fix any small issues and overcoat it... it's a good trim and base...
spraying outside? just don't paint in the spring with the green pollen!
