Hi ChaucerC, I too am relative newbie , Enjoy your car. I found some brilliant stuff for the exhaust at a car show last year. also available on Fleabay. It is apparently what the American truckers use on their Big rigs for the Stax etc ...takes the heat well. Does seem to hold a shine, before discolouring, longer than Autosol and Autoglym. Although a lot more expensive , approx £18 for 355 ml. Only a small amount is required and a great shine if polished off with microfibre cloth. I guess expensive because it is brought over from the States It is called White Diamond . Cheers, Chris
