Today I dropped off a big load of parts to be powder coated for my Omni GLH suspension/chassis overhaul project. While I was there, I noticed that they had some very large (truck) coil springs that had been coated gold and hanging up and cooling.

Should I drop off the original coil springs for my Omni to be coated? I guess I was under the assumption that they would be damaged by the heat of the oven, but if they can be coated safely I'll drop them off with the other stuff.
