Just purchased a shoe box full of diecast cars at an auction this morning and one of the cars is a dark chocolate brown ford mk IV. Car almost looks like it was never really played with, but it has one major problem... Someone painted the roof, front and side windows. Doesn't appear to be nail polish, there were plenty of those examples in the box looks like it might testers or some other model paint. Anyway to get it off without destroying the original paint and windows? This is one of the darkest brown redlines I have ever seen and would be beautiful if not for the custom paint work. I know this has probably been asked before, but any help would be appreciated. Thanks.
