First go to Home Depot and get another regulator and a moisture trap add trap to the air outlet and then the regulator, you can control the psi. Get an in-line moisture trap and add to the hose. The air cannot be too dry.
Wildlife colors are nice and thin but some of the colors like to tip dry very quickley. You need to get some extender and follow the directions to use. I shoot wildlife colors also but for thin lines I shoot the paint at 10 psi also.
What brand of brush are you using?
You can post the pic right here on this thread and fourbizz, ernel, dampeoples and others will give you all the help we can. Don't be afraid to show your early work, I've been painting baits for close to 5yrs and I'm still not as good as I hope to be.
