I want to put some omni urethane paint on my K5 this weekend, but the weather looks like it may not get above 60 degrees. Should I get one of those propane tank mounted heaters, heat the garage, turn of the heat, paint, turn heater back on? I am worried about blowing myself up. Also, is there any reason not to use halogen lighting while I paint? I know they get very hot. I put the primer on this afternoon, and I need better lighting. Thanks.
