Wow, I didn't know that. So how come I notice them getting more corroded only right after I wash my car? And if all rotors do that, how far does it corrode? Until the things look like a piece of rusted metal?
Ah yes a fact of life all things decay eventually. Steel will even rust in a vacuum. Ask a metallugy major or a Navy person that's been station at sea.
Living in Ohio for most of my 56 years, controlling rust is a major priority for the car buff and the home owner.
Here's what I will be doing with the new rotors Stazi's suppose to be sending me soon ( Hello Stazi are you listening Hi Hi)
I use three different coatings on new or lightly rusted rotors and drums. Even do this to brake lines, certain underbody parts and seams with spotwelds that hold moisture & etc. I have to keep this car at least 12-15 years, besides it the nicest drivers cars I've owned of Fords. Beamers etc way too much money.
These are all Rust-Oleum spray cans. numbers above the Bar Code!
1.7785 Galvanizing compound ---I even spayed this on rusty exhaust pipes, but as soon as the salt/miosture gets on the pipes, the galvanic action/corrosion starts and the zinc in the coating becomes the sacrificial element and you have to re-coat in the spring. It's all about slowing down the process, we can't stop it.
2.7584 Cold galvanizing compound very heavy zinc. For those who live in non salted roads you could stop here, if you want the silver look. It's easily touched up.
3. 7716 Heat resistant silver for the Top coat. It's also in white and black.
My calpiers were also coated several months before my 98 Mystique's first winter.
Try to keep as much of these coatings off the wear areas. yes you will never keep the rust off the wear areas. The zinc part is not that big of a problem as paint. "Build up on the pads.) That's just the way it is. Nothing is forever and that's what the auto manufactures are counting on. "Planned obsolescence's" Right?
Any questions for the "Ole Fart" no problem.
