I recently read a nice review on Glare and how well it polishes chrome. It's a little pricey though...... I read that it is sold in Honda stores under their name for much cheaper
Wenol Red and Blue makes for show level chrome shine. Red has some very mild abrasives but Blue is pure shiny in a tube. Germans have some really good chemists.
Mothers chrome polish for me or if you really need to lean up any metal use Flitz polish (German manufacture)
When i bump the rear exhaust pipe down low where it goes into the 2 into 1 section just aft of the floor board i get boot heel marks on the chrome heat shields. Mothers chrome polish takes it off. It requires a little elbow gease but repeated applications will eventually remove the black marks.
