I am pulling my hair out here. I have been using a Porter Cable HVLP conversion gun for about a year now. I spray a lot of water base poly, and laquer with it.
Anyway my major problem is with an orange peel finish. I usually disregard it because I use a satin finish, and it doesn't show too bad. But on my current front door project , I'm using a Target waterbase gloss eurethane. I'm sick of resanding out the orange peel and trying different settings.
Problem is this gun has 5 different variables, and unfortunately I don't have the super secret decoder ring. There is psi, air volume, material volume, tip size, fan size, and thinning. AGGGHH!!!! So I've got a one in a million shot of getting the right combo to having a perfect flawless finish. I increase the air pressure and I get a finer spray, but then it dries too fast and the overspray fouls my nice finish. Decreas the pressure and the orange peel gets worse. Increase material flow, and it globs and splatters, decrease and it is spotty, change the fan size and I get runs....
So, does anyone with experience with this gun have the "MAGIC" setting to eliminate orange peel??? Any advice would be greatly appreciated.... I'm thinking maybe thinning it a little more, but I don't want to waste much more finish on "experimenting".
Thanks.....
