I've been painting various parts of my tractor, and I've done the sanding thing, the cleaning thing, the priming thing and now 2 coats of finish painting. I've been using a 75 watt light bulb with one of those aluminum reflectors behind it to see what I'm doing in the basement. I left the light on after painting and the heat from the bulb seems to really help with the drying process. I think I stumbled on something here as I'm getting the best results of my life here. Just thought I'd share this.
