I am not disputing everything you say, what should I do if I disagree with you? I thought discussions were to learn and swap ideas not to get nasty with someone who disagrees on a fundamental point.

There is a big difference in stripping powder coat and chrome. Given enough time talcum powder would strip chrome but we have not got an eon. Stripping chrome this way it would be very hard, probably impossible, not to damage the alloy. You would have to get all of the chrome in one even blast as going back over a spot to remove a spot of chrome you would blast an area with no chrome and abrade that area too much and leave a hollow around the remaining island of chrome.
I agree that stripping the chrome is ideal but possibly not practical in this case. A fine sand or glass blast of the chrome would supply an adequate base for the pc.
