thread on the gun as in the one that determines how much paint comes out? yeh well i have been tryin to get it wet on the first few coats so thats my problem.. noob painter you see. Ill try giving it a buzz with the 400 grit and do as you suggested datto13b. Im also doing it outside, well in a shed but there is no heat lamps. Not being dry till the next day is not a worry. Im also using fast hardener.. what sort of air pressure is best to use? the guns that i bought say the opperating pressu9re should be around the 30psi mark, which equates to approx 8psi outlet pressure..

thanks heaps for the info boys
