Just a random thought.
To avoid the baking which is part of the powder coat process, a person could do an epoxy prime and aerothane finish on the airframe.
To save a few bucks on the kit, we bought the frame bare, sandblasted in the driveway and did the above mentioned painting. Turned out really nice. I like the sandblasting process - gives a person a chance to thoroughly inspect all the welds.
I am not do sure the parts mentioned would survive the 350-375 degree F temps. I would even be a bit concerned about the effect of the heat on the temper of the aluminum push-pull tube.
