I have a G29 that I had ceramic coated when new and one year on the paintwork is in immaculate condition. However as hard as I try I just can't get it (Portimao Blue) to showroom shine. I have tried so many common and readily available polishes and gloss enhancers, mainly from Halfords, but am I missing something or not tried something I should.
Or is it something with the ceramic coating that is stopping that showroom shine?
