I've just recently read the last two issues of Street rodder, where the had a two part series on painting your own car. I decided to give it a try on the truck, and was reading up on drying out you airsupply. I came across several different inline or what I believe are in line water and debrie filters. Am I correct in assuming these can be screwed into the air hose prior to the paint gun and pressure valve, downline far enough from the compressor that the condensed water will form and be filtered out. I don't have a plumbed compressor line with any water trap, and was wondering if one of these would work?
