stripping combustion canon

Recently I was showing one of my children some of the very cool -looking launchers on this site when my 7yr old asked me why I hadn't painted any of ours...I hadn't ever given it any thought before.So,he and I went shopping for colors...Plasti-cote:green, red,blue,yellow,& chrome.
Everything turned out beautifully; gave me a chance to teach #3 something #s 1&2 missed out on...
Anyways,I hadn't given it any thought until I began to re-assemble them all, and had put the last one together (the 'Intimidator" or as my wife puts it ,:''OH MY G-D ! Wrap that thing up in a blanket and don't let the neighbors see it" canon when we leave to go shoot) ,but apparently the chrome spray-paint has a high enough metal content in it that the ignition spark is conducted all-across the outside of the chamber;hence,touching the chrome and a bolt head allows for a noticable zap!
It took some time to troubleshoot where my spark had gone,as I was less than alert down with the flu...
Anyway, my 16 yr old pointed out the spark jumping from the chrome paint to the bolt.
The chamber is sch-40 non-metallic underground 4" conduit with two sch40 black ABS pressure rated milled couplers sleeving where the 1/4" electrodes go into the chamber. What solvent(s), if any can we use to clean this chrome paint off without destroying this old beast?
