just a tidbit of info to think about on this part of the process. and not to say that mike is wrong, it has most likely worked and been right for the parts he has done. when doing small, lightweight or tubular parts the part will come up to temp fairly quick so mikes process is most likely ok. on heavy parts like engine block, wheels and such the difference between flow out, which can occur between 275-350 degrees, and the final cure temp of say 400 degrees may take longer than the 25 minutes. and the cure cycle truly doesn't start till the part gets to say 400. i know this is nit picking but it can save a job from redo. it is costly, but not as much as a hobby gun, invest in a laser thermometer. it will save headaches in the long run on larger parts. especially if, like me, your oven is slow to come up to temp.
