I did not heat it up. I goes on with a fine spray but covers extremely well. This was a quick light coat follow by a second one just a few minutes later. Dries to the touch in about 10 minutes. I looks like I have about four coats on it. For the price it is definitely worth a try. One thing I'm confused about on these "any angle spray" nozzles. You can't hold them upside down a clear the nozzle but yet the don't clog??? Gotta love that and it saves paint.
This is not necessarily true. Most Bilge blowers are just that, blowers. They are not in the gas fumes, they just blow fresh air down into the bilge forcing the fumes out vents. The fans that are in the bottom of the bilge are squirrel cage fans with the motor in a safe place. The only hood fans that would be safe, again would be the ones with the motor outside the air flow. Most fans in above stove mircowaves are that way. The Jen-Air down draft is a large squirrel cage fan, may almost me too much for a small paint booth.
I would say it's mostly the fan. Any motor that is not explosion proof in the air flow can spark. I can say that I have had a few computer fans melt down in my computer. It would not take much paint build up on one of those fans to cause an issue.
Not sure what you are asking here. I do know how to make babies. There are several 1/18 flathead hot rods made, and it is a lot fun swapping engines in them. These just came in Friday. There has been a few diecast 1/18 kits made going back to the 60's with the Hubley Duesenberg. I can only think of one plastic kit, a Corvette experimental. Send me a PM if you want more info.
