Was monkeying around with the compressor,finally bought a moisture trap at Homey Depot,found out it needed a coupler,thanks campbell ;-( later,was at WalMart for other things & figured I'd check for a coupler,found the above mentioned dept,& thyey had it!,but had to buy a 4 pck that included the coupler I needed,AND they sold moisture traps,the same frickin' one that Homey Depot does,just a different name- Huskey.1 step closer for painting,next step: filtering for painting.
