Tried powder coating a wheel the other day not sure what or if I did anything wrong. I got my oven unto temp (180 deg) set a wheel up, earthed it, dropped my pressure down tp 25/30 psi and proceeded to powder coat. pressing my pedal whilst spraying/dusting the powder on seemed to look even and ok, so I thought.. When I put the wheel in the oven the temp dropped to 165 or summit quite quick so left it in for 15 mins instead of 10 don't know if i did rite or what. On removing the wheel there's a couple of runs (which I didn't think would happen) and quite a few dry bits which looks like not enough powder was on. Any advice kindly accepted. Thanks
