[Land-speed] Plating

[Bobbyhotrods at comcast.net]

Finally a topic I know a little about.
Dick, pickel (HCl) will strip the chrome quickly, but not the nickel.
There's only an immeasurable amount of chrome on a "chrome" plating job.
The nickel will be unaffected. The special strip a plater would use is a mess to dispose of legally here; they usualy polish it off.
The "reverse plating" technique Otto mentioned won't work well, a plater won't compromise his tank anyway, and the sulfuric bath Bob Denton found will attack the steel to some degree.
I'm afraid you want to drop back and punt, and send it to a plater with a nickel strip. Forget about pickeling it at all, the flash of chrome won't matter. 
You'll need a nice finish before "bluing", so you might want to find a house that routinely does this gun stuff. My 2 cents. BJ
