I am trying out my new Dremel tool on a old sissy bar. Looks like it will still be lots of work on heavy rust, but this is gonna be awesome on my nice bikes to shine up and polish the chrome! Put a little Turtle Wax on there and buff it with my Dremel and watch it shine! I was told to try Evaporust , gotta get some of that. If anyone has any suggestions please pass them along, on how to combat that hard rust!
