Removing Chrome
#12
I soaked my brain in coke for years, many the morning I wiped my brain out of my nose!!!

I have found the same issue in my area. One powder coater said they would media blast the chrome but wouldn't stand behind it because the parts are footpegs and they weren't certain if the PC would stand up to the abrasiveness of ones feet. I was considering wire brushing the chrome finish and then having the PC people blast it.

If the chrome is solid and intact, a frosting with the media blaster to give it some "tooth" will be fine. Sometimes, loose or failing chrome will be exposed at this point. Flaking chrome can be scraped and sanded, preferably with some type of power sander, to remove the bad spots, feathering the edges to where the chrome is solid. Occasionally, weak chrome is revealed during the heat curing process. Usually, this may occur when the curing cycle is too long and/or too hot. I've powdered a crap load of chrome and it's still good. The entire front of my '05 Sportster Custom was powdered, among other parts.
The worst part about powdered foot pegs isn't your boots' sole, it's the little, pebble-size rocks that get stuck in the soles' lugs. When they get to looking like poo, powder them again.
Wire brushing before media blasting is pretty much a wasted effort. You'd be better off with a scraper and sand paper, as mentioned above, to remove failing chrome. An experienced powder person shouldn't have a problem with powder coating chrome. Some shops will warranty powdered chrome and some won't because the substrate, the chrome, may fail under the powder. I feel like if the piece is prepped proper, the powder "envelopes" the chrome and helps hold it all together, but I have no evidence of this and I don't know Jack.

On a serious note, Sandblast the parts first. scotchbright and 200 grade sandpaper is not good enough.
