Thanks so much for the very complete run down on keeping the polish on the aluminum! I've got a month to spend now on it due to a wait to fix up that mistake of a design in the Brooklands exhaust. I'm probably the last of the 50 M3W Brooklands to get it done....I am just shy of 1000 miles....put almost 400 miles on since I had it delivered. I sure wish the previous owner had dealt with it, but at least I have the benefit of all you fine people sharing your knowledge!!
