I recently acquired a heater - medium-wave, 1500 watts, quartz tube bulb.
After I spray the second coat of clear (PPG), do I immediately use the heater or do I wait a while for some of the solvents to evaporate? Thank you for any advice.

I suggest you go to ppg.com and find the auto finish section. Find the product sheet for the clear you are using. These usually give the temp to bake at for how long and how long to wait till you start cooking it if there is a wait. http://www.ppg.com/cr-refinish/phase...Info.asp?Cat=9

With a medium wave its not necessary to give the last coat of clear a 1-4 minute flash time.
Won't hurt and really would not help.

With a short wave its a good idea to allow for a flash time of 2-4 minutes
as a matter of fact a lot of short waves have a flash timer built in.

Also if this is your first time using this type of system keep the lamp about 2.5-3 feet from the panel, paint looks awful when it bubbles.

I remember back in tech school, I was given a football helmet to paint in one of the local schools colors. It was told to use sikkens autocryl, and I don't know what it is about sikkens, but I would always get a run somewhere whenever I used it. Well anyways, I painted the helmet and got a pretty decent run and I stuck the heat lamp on it. I had it fairly far away, and when I walked off to another task one of the instructor moved the lamp closer. Well the paint didn't bubble, but the helmet was lopsided and warped. watch out when heating any plastic parts.
