Rusty car rotor

Well, the "hats" aren't painted, that's why they're rusty. Wire brush them and paint them with something. Looks like you have a little rust problem with your lug nuts, and your tires and wheels could use a good scrubbing. Time to fill up your AG cart!

Yeah u just got the car getting new wheels and nuts and what would u recomand them to be painted with thought if they were new they would not do that cheers
 
Some replacement rotors come with the non-friction areas painted, some don't. You can use any paint really, from something from the local hardware store to caliper paint from Eastwood (if you're in the US). Just make sure if you're in the hardware store you're getting a paint that's made for metal substrates, and you may need to prime it first. Usually your local auto supply store will have something for this.

-Paint 'em with POR-15 Ceramic paint.

-Don't worry so much about painting along the fire-path...
First time you brake, the paint in that area will "burn-off".


-Next time the need for rotors arises try to opt for:
1. Zinc washed (Good)
2. Cadmium plated (Better)
3. $$$$ Carbon Ceramic $$$$ [Best (so far)...but: Ouch!!]

If you use Por-15 you should scuff the surface and a trick is to poke two holes in the can and pour the paint into another container and use two sheet metal screws to seal it up.Wear gloves as it`s a difficult clean up.
 
I had a few sets cad plated. A friend of mine uses a big plating job shop and can throw in my rotors for free. The cad plating is still nice and shiny after years.

But the rotors on my Cobra are all two piece and the aluminum center hats don't corrode.:xyxthumbs:
 
I love my aftermarket zinc coated rotors, only rust that sticks around are inside the slots.
 
Por 15 works great i have used it on my rotor hats . And yes wear rubber gloves. If you get it on your skin and it drys you will be wearing it for a week been there done that ! Lol
 
Wait so you guys paint the actual rotor?? Im new to this and Im damn sure that i come across the same problem once in a while. I dunno what por15 is but im about to go crazy on it if it works lol

I see it as being the:
Same principle as the rotors having a Zinc or Cadmium plating:
Assistance in keeping 'rust' at abeyance.

IMHO...
I figure painting the rotors won't break any of the: "Thermodynamic-Laws"...
at least to the exstent of not being overly deleterious to the braking-system.

This discussion seems to fix the rust build-up on un-swept areas on a rotor (single-piece or two-piece). I have used POR-15 on all unswept areas of my two-piece Stoptech ST-40 rotors and it has held up well after initially applying 2 coats but it has started to wear off in it's first season.

The other rust concern is the initial build-up of flash rust on the swept areas of a rotor (rotor face) after washing a vechicle or specifically the wheels and brake assembly. Is this an issue that people want a solution for?

Yes, what's the solution?Feed back please
 
Use "caliper paint" available at all local auto parts stores.
