You can paint them, it's what I did, some VW dealers are known to do them for fussy customers too but I would rather do it myself.

Have you been driving enough!? :D
They're only cast iron so it's not surprising to see rust on any disc if there outside and not used...

I think panhandle is talking about the disc hubs Roxy, not the parts of the disc that contact the pads during braking. These can rust over quite quickly. They didn't rust at all on my last Roc (MY09), but at less than a month old, the ones on my new car have started to rust.

This topic was made a while ago but it's still relevant - I think it's ridiculous that Scirocco brake discs should rust no matter how often/little the car is driven. The discs should not be made from a metal which rusts easily and the suppliers are a joke to produce them for such a good quality car. I'll be the first to admit that my Scirocco does not get driven daily but the fact that all 4 discs are terribly rusty after only one year annoys me. Whether it means re-painting them, asking volkswagen for new discs or just living with the fact that I have a stunning car with unattractive and clearly seeable rusted discs, we shall wait and i'll keep you updated!

So you do understand why the discs are made of Iron right?
Iron has a very high melting temperature which is good if you are planing applying heat to them..
Also iron is cheeper then other materials that could sustain the temperatures involved.
Iron rusts quickly, but its only a thin coat which will be removed as soon as you go for a drive.

So unless you want to buy some carbon ceramic ones i think you will have to live with it..
..or just drive it more, which should not be a problem since they are so fun to drive :D

Rusty hubs seem to be a problem on every VW I have owned and seen. You can paint them, but even then will probably rust through again eventually.

If your planning to paint you should wire brush the rust off the hub and only stop once the surface is fully free from rust then paint front and back with suitable a high temperature paint. Factory dipping with a high temperature paint then grinding the front and rear friction surfaces would solve the problem of rusty hubs, edges and internal structure for light users but a heavy user would still find the paint flaking off due to heat.

Non metallic discs or two part discs and alu hats are only real solutions to not having rusty hubs. , carbon-ceramic discs at a couple of k each soon makes it obvious why fitment is limited to very expensive cars..

I cleaned mine with brake clean and a scotchbrite pad and painted them with an aerosol of silver hammerite. I did my Golf with the same and in 3 years it never burned or rusted off, and the Scirocco has been fine for 12 months.
