Oh I got it up to the recommended temps, just took a lot longer with
only halogen lamps instead of infrared.

The baking process is only for flowing the powder into a continuous
plastic layer... baking it too little would result in crumbling from
lack of melting, way too much heat or time would get you brittleness.
But as long as it flows together it's pretty much fool proof.

For what it's worth even with my makeshift heating setup, the coating is
too hard to even effect with a fingernail or a coin (wont even dent) it
takes a sharp knife to even gouge into it... compair this to keying a
paintjob... no way a key even leaves a mark on this stuff it wont even
knock the texture bumps down leaving a glossy spot :)

Sounds fun. How large a piece can you do with these setups?

well I did my old 4.2 valve cover and had to move the lights to get the
ends to melt. I wouldn't go much bigger.

With infrared heaters the sky's the limit, someone had an entire jeep
parted out on ebay last week, powder coated tub, fenders, windshield
frame, roll bar everything down to the frame.

I was waiting on some crane "anti-pump up" lifters to continue on with
the 4.0 head swap, so I got this system, now I'm thinking of all sorts
of stuff that would be better coated with plastic :) brackets, caps,
hood prop... brush bar, bumper... my steel wagon wheels
