Steel + water = rust! Nothing you can do about it. Dont get hung up on it!
Since my car has 4 years of warranty and I bought the "Audi Fleet Comfort" package. The package includes all wearing parts including the brake discs and pads. So I won't consider changing the discs myself.
But I'm wondering why the heck Audi can't just use a rust-free disc.
Your disc proves that it is possible.
I also had the rusty hub problem on my S3. Going to get the hubs painted with your recommended product, thanks!
Wow looks so much better
Here's my STD OEM rear discs, Gorillajeabus, with POR15 coating and 3-years of running to include 3-winters...

Mmm, I like that. So you sanded back the disc, then coated with POR15? Did you give the backing plate behind the same POR15 treatment? That looks immaculate! I like!
Just a light sanding on the hub to provide a key and no more and then POR15; and yes AudiNutta, clear POR15 on the back plate
POR15 is an excellent water repellent...
How did you apply the por15 clear 45bvtc?
I'd like to coat underneath components with it. I have a two post lift for easy access but don't want to spray it does it brush on quite easy?
Another quick question have you every used or tried the bilt hamber stuff hydrate I think it is.
Brilliant that's great thanks for that. Another quick question have you every used or tried the bilt hamber stuff hydrate I think it is. Think I'll go porntho esp since it is brush on and will be relatively mess free. I remember doing my focus Rs a few years ago in 2011 and used the wax oyl brushed on it went off soft and sticky Matt black suited the car fine and lasted well for the two years after it. But would rather the clear stuff this time.
Interested in the mod for the seniors as not worried about having them. I can tell who my brakes are worn.
thats what I was looking for, that flower thing thats joined to the disk, mine looks dirty and horrible, is this one treated?No experience of the Bilt Hamber products; I used POR15 following my use of it on rusty brake calipers: the brake calipers (non powder coat) of both my Audi TT and Audi A2 have been 'restored' with POR15, I tend only to propose products I've handled myself and seen the long term results. I also use POR15 on my front brake discs; ok, so it yellows, but they don't rust
Not bad for 4-years of use; but then again I don't use OEM brake pads...
thats it then !No patters, but I did try once with POR15 but removed that and it was out with the Dremel and some 'metal' cutting and polishing compound (Ebay) finishing off with Solvol Autosol - and to be honest the spiders now stay lean with no more attention than the rims get and that's with a 5% domestic Flash to 95% tap water spray on and wash off and no worries...

Note: the sides and surfaces to the rear of the polished spider front face are coated with POR15 'clear' and it's an excellent water and dirt repellent - hope this helps
thats it then !
I done it on one anyway, do the other tomorrow, before and after (different wheels actually, because I never thought of the pics until I had done the deed!)

Where's best place to order the clear POR 15 ??Just a light sanding on the hub to provide a key and no more and then POR15; and yes AudiNutta, clear POR15 on the back plate
POR15 is an excellent water repellent...
Thanks for that info, I will see if someone has experience with the clear stuff. If your wanting to sort the orange use hamerite silver as I've used that on cars over the years and won't discolour....I ordered the silver POR15 to use on my S Line, I took it for one spirited drive and got alarmed by clouds of smoke when slowing for a cattle grid. The paint has only gone and turned orange, it looks horrendous. It is bright, electric orange on the worst part of the discs. I'd recommend to avoid the coloured POR15.
@B19, I got mine off eBay for £28.

Thanks, I'm sure you will have a RS3 soon FL or second hand on the drive, I hate cars with rust on discs so I just need to protect my new ones, my car never sees rain but washing car can mark front disc hubs,,, I've a A3 sline 14 Tfsi like yours in drive too, nice car and just looks and drives like my old S3 15 plate ( without the 4 exhausts )No problem, the seller was great. I can get the name if you want? I had issues getting the tin open because it had leaked and dried rock hard. So I had to totally destroy the tin to get it open, I complained and he informed me that these tins are designed to be one time use (seems a bit silly), but none the less, he gave me a new one out of courtesy.. not bad for him to send it out so willingly being worth £28 if you ask me.
Thanks, I will have to look at that if I did try and get it done again. I only used POR15 because of the good reviews on the forum. I bought £1.99 calliper paint for the callipers and haven't had any issues with that, it's bonded extremely well haha.
I believe all experiences with the clear POR15 are good, from what I have read previously and I will for sure get some when I finally have an RS on the drive :-(
