Here's a litte write up I did (apologies, VW not RS)...
First I picked up a can of Halfords finest brake caliper (HT) paint. Hammerite Smooth is just as good & often available in more colours, not to mention cheaper!
Pop the car up on axel stands ( I did one side at a time ) & drop the wheels.
Grab yourself a nice big wire brush or an attachment for your drill & have at it with the brakes.
NOTE: You will sneeze/cough/spit black if you don't wear a face mask!
I happened to have some painters masking tape lying about but any will do. Mask off everything that you don't want to paint, valves, pipes & disks being the obvious.
It says on the can that the paint is 'touch dry' in 15-20mins. As it was flippin' cold I had to double that & at one stage resorted to placing an electric heater under the wheel archs.
Anyway, I had done a blinding job cleaning up the calipers but had no primer I decided to put a thinish first coat on.
Please excuse my naff camera phone pics. I can assures you the paint is bright red not barbie pink!
Once this was dry (both front & rear) I put the second coat on.
It started too look pretty good, after it had dried I was happy with the finish & voila.
With my filthy wheels back on I think it gave the car the 'right' look!
Probably a bit straight forward to warrant it's own write up, but you never know, might help someone!
