As many of you know, my "real" job is metal fabrication (sheet metal, wire
forming, tubing, welding, assembly, etc.), and we have our own plating and
powdercoating lines (fluidized bed, and electrostatic spray) in-house.
Powdercoating of wheels would be electrostatic spray, and oven temps are 350
degrees F to 500 degrees F (usually 400-450). The oven temps depend on
powder type. Anyhow, these are hardly temperatures that'll heat treat the
alloys and change thier molecular structure. However, those temps will
damage wet paint. Anyhow, long story short, to properly powder coat a rim,
they have to be bare metal (either have them bead blasted, hand sanded,
whatever). It's also worth noting that powder coating is a durable surface,
but is subject to getting cut. Anyone having tires mounted must make sure
they have newer "low contact" mounting machines, as the edge would be subject
to wear on an older tire mounting machine.
Usual power coating color for rims is flat black. Anyhow, if there's
interest, I could have my estimating staff figure out some pricing to do a
group of rims, especially if it's a standard color.
