I am not sure if this is in the correct forum, if not I apologize. I did a search on frame polishing and frame cleaning but did not find much so I will ask. I have a 99 CR 125 and no matter how clean I get it the frame never looks good enough. I have seen many CR's with polished frames and love the way it looks, but I know that may be a pain to keep up, but have no idea either. So I am looking for any suggestions on cleaning the frame. I have some mothers metal polish that I use on polished car wheels and know that will do the trick, are there any reason why I shouldnt do that? Will polishing really cause cracks to form in the aluminum??? Also, are there any products that will clean and help get rid of srcatchs in the plastic??? I saw a product called "plastic re-new" in some magazine but have yet to see it at any mc shop. Thanks in advance. :)
