I have been powdercoating almost everything on Spridgets for a few years now.
I have the Eastwood $100 kit and an oven I picked up in the trash.
I do certain screws and bolts, brackets, most suspession parts, And things like the shifter tin gets powdercoated as close to the car color and then I paint over it. This way when, not if, it chips, it doesn't look that bad with the powdercoat under the paint. I even use off white powder for many parts on an OEW car since it's a dead match.
