Quoted from bam10:Im not sure if my opinion is what you're looking for as I've only cleared about a dozen playfields but I do paint for a living and I spray clear every day.
I never see anyone using a syphon fed gun, gravity fed is the way to go. Personally I prefer sata but I have switched to iwata because the paint transfer efficiency is so much better. Its amazing how little clear these guns use and they spray well at a much lower pressure (as low as 16 lbs). As far as cups we use 3m PPS system instead of plastic or aluminum cups but im not sure thats cost effective for occasional use.
Which Iwata gun do you use?
