Just took the plunge and ordered materials from Stewart Systems, it's a water based/waterborne covering system. Probably breaking new ground here, but what the hey, somebody's got to try it. Reasons to try this product is that winter in Alberta can get to 20 - 30 below F. I can heat the shop to 70F, but if I turn the furnace off so I wouldn't light off the fumes from solvent based systems, the shop temp would drop fairly fast. If I used fresh air exchange my furnace would be running 24/7. Has anyone tried this system yet?
