Spraying outer brake discs??

[Wozski]

Has anyone sprayed their brake discs with a high temp clear lacqeur or similar to stop the rust from forming on the outer edges Spraying the outer edges only!!)?
Is it safe to do so?
cheers

Brake disc's rusting is a unfortunate side effect of the material they are made from, not much can be done with them as they will rust eventually no matter what you do to them

Spray them with black Hammerite smooth. Ive done this before and will do it on my S3 when i have time.
