I have a GR and i've seen others polish their manifold and it looks like brand new!!! Just wondering what sort of materials do you guys use and how long it takes to polish it?
Most electroplaters provide this service. I've had various bits done on other cars & they've come back looking sweet. When I can afford to have my GR off the road for a few days I was going to take it up to Artarmon Electroplaters.
