After the miserable struggle I had keeping the dirt out of the finish with the last door set I decided to step up the game a little.
I was able to get a 'decent' topcoat on the alder pair by resorting to my old automotive garage painting tricks. Wetting the floor, sanding the night before and letting the dust settle, ect.
It just became blatantly obvious that until I could design and build a proper spray booth (which I have a slick design going for), I was going to have to start tenting. This temporay tent set up using zipwall poles and visqueen will help provide a cleaner enviroment for finishing.
