Painting brake discs?
After a year of sitting in the garage (on the car) my brand new discs have now got a thin layer of surface rust on them and now look decidedly second
hand  Even worse, they are clearly visible through my Compomotive rims. I realise the pad area will be nice and shiny after a few presses of the
brake pedal but everything else will remain rusty.
What is the best way to pretty them up a bit? Hammerite ok?
Cheers,

I've used silver paint similar to hammerite on my volvo discs and kit car - so far it is still on. If you foresee getting you disc red hot,
then proably no paint will survive that - maybe High temp paint would be better?

yep use high temp paint, black exhaust paint from halfrauds is pretty good stuff, I do all my brake bits with it, certainly unless you drive very
slowly or never brake any normal paint will soon burn off the discs.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I wire brushed the rust off then used Halfords Hi temp stuff.
Most paint will come off in due course so i regard this as something to be done once a year or so.

I've had good results with Sperex VHT spray paint, comes in a few colours aswell including silver.
I got mine from the local motor factors.

Mask off the clamping area where the rim touches the rotor. Paint is just like dirt and can cause clamping forces to be reduced over time. Probably
not an issue in this case, but may as well avoid it.

Good point - I had a strange wheel wobble on my Nissan which turned out to be a very thick coat of paint on the disc mating surface causing a small
amount of runout. I sanded the paint off and all was well again.

Before I fitted new discs to my road car I masked and painted them with exhaust paint from Halfords. It needed curing so I stuck them in the oven for
a while to help it set, they stayed nice and rust free for two years. Didn't have the time last time and the disks have gone rusty very quickly.
