I'm interested too... How much are you into the powdercoater for so far, $$$-wise?
The Larry Lyles book "Project Charger", about restoring a 1970 Charger, has a lot of info on this system, which he uses with a second-hand kitchen oven that he bought for $50. He has a lot of tips about pre-treating and cleaning old parts before coating.... and a great read with lots of good resto tips anyway...
I want to get this rig too, but where do I put the oven?? Grrrrr.. need bigger garage....
