thanks, I used to build complete gas stations, truck stops etc. from the ground up, I stick to the interior framing drywall ceilings etc. now bid a job in owosso, michigan was scheduled to start in august, well with delays ended up starting January, was one of the worst winters we had in a while very cold and alot of snow, we had air nailers that were freezing, used antifreeze lube in the lines after a while go no, so we built a dog house to contain the compressor with a water trap inside threw a 500 watt halogen in inside it, back in buisiness, last exterior job I've bid, been about 10 years. your story reminded me of that, great minds think alike.
