Well one more little treasure that has turned up is a pair of these S Discs dated 1990. Do I recall the hub bit being painted on the originals? Or were they bare metal? I think the hubs themselves were bare metal weren't they???

The rust is so surface that it comes away with ease, a little job for tomorrow

So do I paint anything folks?

I paint the not important surfaces .. does it matter what OE was ?

I blasted and painted everything on my OE discs with aluminium-zinc spray, even the friction surface slightly, to prevent immediate corrosion until restoration is finished.
Rather have non original paint on than original rust.

I'm planning on using the Frost brake grey on the non friction surfaces to stop the rust on my NOS genuine discs Andy.

I toyed with leaving them 'au naturelle' but decided the inevitable rust would piss me off.

Me, personally, I'd get rid of the rust the least abrasive way possible and then wipe down in meths . Prime and paint every non friction surface in heat resisting black (I used radiator paint). On the friction surfaces of the disc, spray with SUPERTROL 001. Leave for a day until the supertrol changes from a thin oil to a thick grease. Put in a zip-lock bag and store away. Suoertrol...... If it was good enough to protect vehicles and armour going to 'the Gulf' by sea as deck cargo, it's good enough for my car - and discs I say.

Don't forget that there's no such thing as surface rust. ALL rust, however deep is surface rust

Paint it will be then. Just been looking at my Aston's brakes and indeed, the actual rotors are bare and that's all.

Thanks for the replies, apart from two spots that needed a wire brush on a drill, wire wool did the trick in seconds. Amazing after all that time!!!

I’m utterly flabbergasted by this thread. Why would you paint the discs? The sweep of the pads will keep the rust at bay. Surely the factory never painted them?

Dr S, "only paint the none friction areas on a Brake Disc & Not any Machined surfaces" ..with the purpose to stop rust

Anyone remember back in the day when Disc Brakes had just started to appear on everyday type cars .. yes it was Trendy to put an oval shape Sticker on the back of the car that just said "DISCS"

Painting discs.....

Sounds like a few people have jumped to a conclusion here??? I am doing the same as on my Aston and keeping the rotors (aka the disc part) clean and painting the rest with heat paint.

As Peter suggests, whilst waiting to be fitted I can then protect them, to clean off before fitting.

Ahhhh....

Lol

Using the Aston original heat paint as an inspiration and after a little cleaning and abrasion, I have chosen alloy colour heat paint as so far, it has lasted about 8K miles / 4ish years on the Aston and, er, I have had those rotors glowing
