How to Prevent Rotors from Glazing Over ?

[Johnny Danger]

Each time I give the Dangermobile a wash, after things dry, I get that dreaded thin layer of rust that glazes over the rotors. And, when I eventually go for a drive, after the first application of the brakes, my black wheels get covered in rust particles. It looks like a canister of orange drink mix has been thrown on my wheels. I've always considered myself a meticulous "detailer", with a few good tricks up my sleeve, but, I've been hard pressed to come up with a technique to avoid this. Anyone have a remedy ?

Wash the car when the rotors are warm and then drive it a short distance (like around the block) and brake a few times but before the water dries on the car's paint and then wipe the car dry and detail. This is how I have battled that for years.

I do have a CDD (compulsive detail disorder).

Really easy. After the wash, get up to 70 mph and stand on the brakes hard. That was easy
, wasn't it?

I guess WD-40 is out of the question.

Get your hair dryer out. Every Boxster owner surely has one in the car to run off the cigarette lighter

I do the leaf blower thing. However, enough moisture still remains on the rotors for the problem to occur.

JD- The dealer once told me of a product that they safely use for this purpose at detailing and for cars on the lot. It is only good for one significant brake application, however, and has to be applied before the water gets on the brakes, so it seemed like a lot of hassle for a little benefit. But maybe if my car spent more time in a garage and less time driving or parked outside fending for itself, this would be helpful. I can't recall the name, but I bet someone at your dealership knows.
I wouldn't try the WD-40 trick --- unless you are tired of speed yellow!

I have just coated mine thin a thin layer of cv grease .

Ceramic rotors $$$$$$$$$$$$$

I figured you get a lot of tang, but I guess you don't want it on your wheels.

JD,

I've used this (and a couple of their other products) when I did a complete brake job on our '10 Subaru Forester about three months ago. Never have seen any signs of light rust on the rotors from all the rainy days we've been having -- same thing with my wife's MB, and I replaced those brakes several years ago. The chemical stays on the rotor. I found out about this stuff from a guy that sells Porterfield pads for Mercedes and includes a kit with the pad purchase.

Paul, it doesn't look as if I can buy just the disc spray by itself. Did you buy their full overpriced kit or just the spray?

^Randall, just try this product:

I no longer have dust issues. I have squealing issues. The spray Paul linked to above would probably fix this for $15.95 a can.

I will start buying and applying the ArmorAll Wheel protectant when I switch BACK to the dirty factory pads on the BMW after I kill the noisy dust-free ceramic pads I have on the car now.

BTW, sorry to detour this thread on rusty rotors!

That's more or less a cleaner/protectant. I'm sure that it does a great job of creating a barrier against brake dust on the wheel itself. However, I'm looking for a trick to keep the rotors from glazing over with rust after washing.

Nothing is going to stop the rotors from rusting after a wash. The Wheel Protectant keeps the dirt/rust from sticking to the wheels so they stay cleaner, longer.

Randall,

I got the kit for free from the guy I bought the Porterfield pads from and paid regular price (what Porterfield charges) for the pads.
