What is the best way to remove this rust and keep it away?
Thanks
Joe

 

It will likely never stay away completely, but I would start by sanding it down and put some high temp friendly paint on it.

 

BBQ grill paint is cheap and works. You could probably use a marine chemical type rust remover instead of pulling them off to sand. This also tells you that the brake rotors were replaced with non Porsche parts as they paint theirs.
How many miles have you put on that new car so far? Welcome to the club!

 

Buy a Porsche disc.

 

Por 15 can be used

Its very good and a USA product so should be easy to get. Its similar to Hammerite in the UK but way better.

 

Exhaust header spray paint works, as well.
One of the colors is a nice, light grey - same color as factory.

Don't use engine block paint ("good for 500 F").
Disc temperatures melt that paint.

 

Nothing like rusty rotor hats to kill the look of an otherwise great looking car. It's all in the details!

I've used silver caliper paint with great success. Sand off all the rust, wipe down and spray. Actually just did this two nights ago... (first time I've done a solo rotor replaced)! The silver very closely matched my rims so I was very happy. (Warning, it's a 500 F paint, see Lonnie's comment above)

it's the rusty rotor hats that actually make the rest of my car look better!

 

i sanded mine and sprayed them with PepBoys high temp paint and they still look as good as the day I did it.

 

You probably want to avoid painting the mounting surface/face where it meets the wheel hub. That could cause inaccurate lugnut torquing.

 

the factory hubs are painted over the whole surface. If the paint is good and dry I dont see where it would make much of any difference with the lugs tightened to the 90-95 lbs range.

 

I assume you painted in place? And what kind of lift do you have? I'm in the market.

Yea I taped them off including the lugs and threw a sheet over the car to protect from over spray. I also had the calipers off at the time. Just tape paper or plastic over them and turn the caliper as you spray.
I have a bendpak scissor lift. Raises the car 48"

 

Pic of mine when I painted the hats on my Zimmerman rotors. That was a fun experience doing that in the parking lot of my town house complex - thankfully have a house and garage now.

 

Cool..Thanks..I think that's the one I'm going to get. So much easier than messing with floor jacks and stands!
