Hi Placo

I used multiple step set/dry paper in the 3 of the finest grits, then pro-grade 3M 'Finesse It', and some wax/metal polish....all by hand (wife thought I was crazy!)

The tips came out great and are an improvement- - -not a showroom perfect look of a new ss exhaust and definitely not like the mirror 'chrome' finish on wheels etc.

hope this helps
