Is there any way of refurbing the gold area of the standard SS Brembo discs? There's a patch of discolouration which I presume has been caused by a fluid leak at some point. Slight rusting also. Where do I start? I don't have any T-cut, but would that be worth a try?
You could try Tcut but I doubt it would work, paint is probably the only option. P.S. if you buy some Tcut and it doesn’t work you won’t have wasted your money, apart from restoring paint its a useful thing to have around, good for cleaning oxidation from electrical terminals, polishing alloy, etc, etc, etc.
