Advice requested: How to keep rotors from rusting

[1953hogan]

Hi guys,

One aspect of my vehicle (2010 Acura TL) that has been bugging me is the rusty rotors which seems to be a common problem with Acura. Below are a couple of photos of my wheels to show you what I'm talking about (sorry for the dirty wheels...has been snowing and salty up here in Wisconsin for a few days now. Just 6-degrees today--too cold to wash!).

After some negotiation, the dealer has agreed to install new rotors for free (they're calling it a one-time complimentary replacement), and I'm certainly going to take them up on that.

The issue, of course, is that there is no guarantee that the new rotors won't eventually rust as well.

I'm looking for some advice as to how to prevent that, and am actually contemplating putting a coating on the rotors such as cQuartz, Opticoat, or Detailers Pro Series, then reapplying it from time to time.

Guys, what's the best way to prevent rusty rotors?

Thanks much,

Steve

I would paint them black and coat them.

You will never stop a rotor from rusting. The poor metallurgy of production rotors is an invitation for rust. You can help keep your rotors looking better by painting the rotor hats, but if it's a daily driver, they will eventually rust. I'm surprised the dealer was willing to replace them for any reason.

Skip the coatings. Got straight to a high-heat, ceramic or epoxy, paint on the rotor hats. Keep anything away from the friction surfaces (the faces of the rotor). While some say it's safe to paint the entire rotor and allow the pads to remove the paint on the friction surface, I prefer not to contaminate the surface or the pad material with anything.

High temp paint works the best. Take them off, sand off as much surface rust (DON'T TOUCH THE CONTACT POINTS), tape off the contact points, paint.

Looks like your calipers could use some attention as well. I'd paint the rotors and calipers to match with a caliper paint kit.

Either this:
VHT Caliper Paint

Or this:

Like others have suggested I would paint them with high temp caliper paint. When I purchased my 2002 Viper I few years back the car was in great shape except for the rotors and wheels. I took the rotors off and painted them with caliper paint. Here's a thread with some before and after pictures. It made a big difference. They still look good.

Dont mean to hijack the post - but I'm new and cant figure out how to start my own post, make a new post - whatever you call it - also not very computer literate. Where do I go to do that.

Just a quick answer will be fine - dont want to start a whole thing - I've read some posts that really went sideways when someone changes topics - sorry.

Thanks

I had the same issue with my TSX. It appears to be a very common trait of the Acuras. I painted mine (the hats and calipers) and they looked much better.
