Thats why I'm waiting until spring until I start painting everything on mine. My garage isnt 24/7 heated but with the furnace and the turbo heater it will get around 60. And I have to blast outside so spring is nice for that as well. Black diamond, great stuff! I have been using HPA 80 lately and it is more expensive but the results are fantastic. It's main use if for sand in a waterjet so it is very fine but still cuts like a hot knife through butter
