To remove powdercoating from a metal surface it has to be sandblasted, chipped, or grinded off. I have played each of these for several rounds, because they are a thick polymer coating, the colors do not fade away like a "charcoal mist" or "oil can" finish would (the powdercoating doesnt look as nice). The only areas where the powder coating has come off is due to bag chatter, not at all where the ball striking area is.
If you look around, most people dont realize, but they have a ton of powder coated stuff in their garage, shed, etc.
An air compressor, auto parts, your rims on your car, if you have an ornamental fence in your yard or area - those are all powder coated finishes, they look like paint, but they are ultra hard, ultra durable, high gloss in most cases, finishes.
Pretty cool really, i bet you could powder coat your steel shafts, THAT would be cool with some cell parts hosels.
