Have recently bought a 2005 A3 3.2 Quattro S-line, the car has only done 10k miles and is immaculate apart from rusty disc-bells and rusty callipers. The discs and callipers are huge and because of the rust look really tatty behind the alloys.

Since I bought the car have obviously started noticing other A3’s and lots look to have the same problem.

Any ideas why they seem to be so susceptible or for prevention?

When I’ve got a bit of time was considering cleaning up the disc-bells and painting some heat-resistant flat Hammerite and possibly getting some calliper paint (just plain black or grey/silver so as to look standardish).

Anyone else done either of these?
