Dealing with Rotor Rust
This process is meant to reduce the amount of rust we see, not necessarily eliminate it completely. I'm not sure if there will ever be anything that will completely stop the rotors from rusting over at least a little. Here's my process that works well (central Florida for reference):
- Clean the wheel and tire and rinse clean.
- Immediately spray Hyde's on the rotor all-around before moving onto the next wheel.
- Finish all wheels in this fashion and finish the rest of your wash process.
- Once the car is finished, before drying, move the car back and forth in the driveway and apply brakes to thoroughly "dry" the rotors.
- Blow off car and wheels/rotors.
- If you want, spray some more Hyde's on each rotor for good measure.
I do this and have pretty good results. I think the drive back and forth in the driveway and blowing off the wheels make the biggest difference.
I've also found that using a spray-on spray-off sealant like Gyeon WetCoat seems to help a bit as well. I use this as a topper for my wheels right before using Hyde's and moving to the rest of the wheels.
