guys i have the hvlp & the gravity gun from harbor frt. the $50 specials. one went bad after a year & i got another. i have 1.4m tip in it. i also have 1.3 & 2.2 nozzle sets i bought with them, remember guys you change needle & nozzle together as a matched set. i used them primarily for primer by opening adjuster out to 2-21/2 turns for primer. base coat -clear coats i start at 1 1/2 turn out on volume knob. by this i mean i scratched a mark on knob when it is fully closed light touch here boys as you are screwing needle into cone, can damage either or both if tight. notice the placement of mark on knob, turn it out till mark comes back to the same position, this is 1 full turn. 1 1/2 turn out is starting point i go to paper taped to bottom of exhaust fan to test spray pattern on. i adjust by amount of paint being applied by pattern i have adjusted to. you want to look for wet spot not on the sheets but on the sheet you know what i mean. you have to determine to your own tempo or speed you are making your pass at to get uniform wet coverage without runs. when just learning guys spend some time testing when you think it is right, mark your spot, go back & try it dry with less turn out & try it with1/2 more turned out to see differences. this will help you to see how it flows, how it runs, etc. instead of seeing it on a fender after it is cleared. i usually end up 2 turns out for clear by the last coat as i run a lighter coat on clear first then open it a little to get it wetter to flow more. i lead my head in front of gun arm slightly so i look back to see the formation of pattern of paint as it is being applied to surface. you can do a $5000 paint job with a $50 gun once you know how to use it. be aware you can't find much purple left on my guns from all the use they have gotten. hope it helps you guys & pass it on as i learned from someone too!:jw art evil:

Hey Vince.

I'm reading some books on painting, (I haven't done any automotive painting yet) and they make the isocyanites in the hardener sound positively LETHAL. What sort of protection are you wearing? Do you use a powered air respirator?

What brand of paint are you using?

THey have them little face masks just about every auto parts store or paint store you goto with the filters and everything like that. Iv been using napa paint. Its good stuff. I would also buy a paint suit to so the lint on your clothes dont stick to the wet paint.

Hey Chris, just be sure the cartridges are rated for organic vapors and are NIOSH certified as such. I wear the Tyvek suit mainly to keep the paint off bare skin, the side benefit is keeping body and clothes lint off the paint job.

I am using PPG paint. I use a 3M dual cartridge respirator with organic vapor cartridges. I only stay in the paint area long enough to lay down another coat, them I'm outta there. Our 34 is going to require more time in the paint area. so I have obtained from work a Scott full face forced air respirator that I will be using to paint the 34.
