I just picked up a frameset that was listed on CL as a 73 Raleigh Gran Prix, but I think might actually a Gran Sport, based on chromed stays and the fact that it's surprisingly light.

Unfortunately it's been rattlecanned black, right over the chrome as well. I know any basic paint stipper would leave the chrome, but is there any way to preserve the original paint? I'm imagining a chemical that interacts with the spray paint but not the different chemical make-up of the original paint.

Grasping at straws, I know! I was taught it never hurts to ask...
