I have recently put a combination air filter, regulator and lubricator on my craftsman air compressor. Before I used to drain the condensate out tank once in a while but I noticed I was still getting condensate in my hose and I have been attempting to srpay paint my models : so this is why I bought this air filter. My question is if I put oil in the bowl which will be for air tools will I get oil int the paint . Or do most people drain all the oil out of the bowl before spray painting.. Thanks Flybye
