A bit of a follow up on this which may be of help, polish factory exhaust:
Here's the kit I used - of course use what you want, its just polishing stainless, pretty simple to do with a bit of time, I left wire wool out you know what it is
I did a test section of (left to right) Metal Polish alone, 0000 Wire wool following by metal polish, 0000 Wire Wool -
clear to see that a wire wool followed by proper polish will work best
So went 000 Wire wool, 0000 Wire wool, then peek machine polished - feedback on lots of other polishes which may help (these are my opinions, I'm just one detailing nerd)
Peek - good cutting and for taking out defects, although creates quite a light finish without that final pop - works by hand and machine
Megs NXT - reasonable cut, creates a far deeper finish with a good level of protection - works by hand and machine
White Diamond - proper bling, but doesn't remove defects well, protection limited, pretty much useless by hand
Properly polished after wire wool, peek, white diamond then topped with Megs NXT - the megs will darken the finish and take away that slightly chrome look the White Diamond does but does offer better protection that helps prevent tarnishing
Both exhausts polished - sports was factory brushed, quiet was previously polished but heat tarnished - both also coated in Gyeon Rim to see how it handles the heat as an experiment (suspect not well but worth trying)
Cutting pads I just used a generic set off amazon (foam and MF) as they are destroyed by metal polishing
Also previous owner scratched both exhausts fitting and removing, so defects removed but above it I now have a foam strip to prevent me repeating when swapping them, worth mentioned for those that swap them in and out regularly
