Acetone is a very strong solvent. The "chrome" on these figures, to my knowledge, is not paint. I am not sure what process they used, but it appears to be a vacuum metalized finish much like you find on a lot of synthetic materials. If it is actually electroplated chrome, even better.
Regardless, the underlying chrome finish is more robust than the black combat paint, so the paint comes off and the "chrome" doesn't. Make sense?
Abnpredator never used acetone on his statue and neither did felmar. Why chance it when it has been demonstrated that non-acetone polish removers work?
I'd stick with the already outlined procedure.
