Interesting question. Although I don't have the answer I do have a suggestion. If you have an old piece of rolling stock or old beat up engine shell you could sacrifice, try painting it with the same paint and testing the paint remover on it.
I just looked at their web site and I don't think it mentions for use on plastic. All I see is Wood, Metal and Masonry unless I am missing something.
