Hi!

I am polishing an Mongoose exhaust to get a nice shine all over. But there are a lot of burned in spots in the tailpipe. I use Belgom to polish it up, but the spots are very hard to get rid of and they stay in. Has anyone a good idea how to solve this?






Also I want to polish up the rest of the exhaust piping. Is it a good idea to sandpaper it first and then to polish it up?
