My tips on my new exhaust is rusting on the inside just one week after having them. What is out there I can buy that will take away the rust, restore the shine, and keep it from rusting again? How hard is it to use? Thanks

 

I saw on the show MythBusters that coke will clean up chrome better than any chrome cleaner out there. I couldn't believe it. So try it out. If it ends up sucking, all you lost was about 5 minutes of your life.

 

I don't know about removing the rust from the inside but a good coat of high quality car wax will stop corrosion on the outside.

 

Sam thing happened to my Camaro, there is nothing that you can do. It is the condensation that is rusting the tip. The only thing that you can get is a stainless steel tip.
