How to help prevent calipers getting covered in crap/brake dust?

[xr2racer]

I'm going to be painting my calipers soon with the tried and tested hammerite smooth.

Is there anything I can treat them with afterwards to help stop them getting dirty? What's ppls experiences like with hammerite smooth painted calipers, do they get dirty quick or are they not too bad?

your not going to stop it really, wit hthe heat changes they undergo the brake dust will soon get build up on them, just a case of cleaning them really, i did my calipers on my trac kcar wit hhamerite and just cleaned them with wonder wheels, seems to have done the job of keeping the dirt at bay.

As long as stuff like wonder wheels and autoglym wheels cleaner works but doesn't take the paint off I can put up with that I suppose
