Please help: I've sprayed three bodies and two necks before. So these two will be my third and fourth necks. Every time I spray nitro I this happens. I don't know if this is called fish eye or what but it's driving me crazy. These tiny dimples where the finish doesn't want to go. I wipe each piece with naptha to remove any oily residue from skin contact and let it evaporate. I'm using Sherwin Willliams LOVOC lacquer and K27 thinner retarder. I run a little lacquer thinner through the gun after each use. I'm using an oil free compressor. I have a seperator and a disposable water filter in line just prior to the gun. It isn't humid in my shop. Temperature is about 50 degrees farenheit.
