Some of my polished parts under my bonnet such as the crossover pipe, boost pipe and fuel rail cover have become slightly faded over time and have lost there shine whats the best way to get that shiny mirror effect back? i saw something on the net doing it this way:
* 220,400 & 800 Grit Sand Paper
* then buff with black jewellers rogue
* then buff white jewellers rogue
is this a correct way of doing it?
