Using the search function, I was able to locate several threads that address cleaning/polishing OTT headers but none that deal with cast aluminum exhaust like Indmars. Do the same chemicals/procedures apply? Is it possible to "mirror" them up? Answers or links would be equally appreciated.
In the garage working on the boat in Utah, United States
It's definitely a pain in the ass. Lots of sanding and polishing. It's worth it once done. It's sometimes worth it to let someone else do it!!! I'm going to have the tunnel ram on my wife's boat polished over the winter by someone else.
