Ok been down this road , last year I stopped at a store ,when I cam out I noticed a broken snapple bottle under my bike ,when I reached under the bike to remove the big hunks of glass the polyester jacket I had on melted ,I mean melted a 4 inch round spot on my brand new 2-1 exhaust system I drove home and used every thing I had that usualy works on boot heel melts, you guys named everything product I tryed in my garage from mothers to goof off from paint thinner to oven cleaner, the next day I went out and bought more stuff about 4 more types of cleaners, Nothing helped at all, and being it was the muffler I knew I could not get it re chromed , I was sick everytime I went to start my bike ,I got sick from looking at this four inch burn on my new 750.00 exhaust, about a month later I was a my HD dealer the service manager walk up to me and said he noticed my exhaust and the burn mark (I said please its a soar subject with me)he said wait and walked back in to the garage came out and handed me a this little deoderant looking pakage and said try this , so I went out to my bike and started using this stick and noticed very quickly it was working after about 15 min of working with this stuff ,it completly got the whole burnt section looking new like nothing was ever there Amazing stuff I since then purchased 4 stick of this stuff and keep it on me where ever I go It Is called ROAD RUB chrome cleaning stick. if you see buy it best stuff I ever used for getting those melted boot marks off .and polyester jaket melts.
