When I shoot my 1.8 tip with Primer, I run 110psi at the compressor and 38psi at the gun. I thin the primer approx 10%. If you're thinning that paint at a 50% ratio and it won't shoot thru a 1.7mm tip then it HAS to be the air setting. Gelcoat is very thick and you can shoot it thru a 1.8mm tip thinned @ 20% but...At 40-45psi at the gun. You have to push it out the tip with the fluid control set high and let the air atomize it. If they're both set to low it WILL sputter and blotch.
I had the compressor kicking out 120psi and I brought it down to 28 at the gun. The paint was thinned down 20% not 50. the data sheet said it is not recommended to be thinned for spray but i was told you could do it up to 10%. I will mess around with it a little more with the air and fluid control next week when I have some time off again. Thanks everyone for all of your help!
