Painting the edges of disks?

[sagekai]

I have some free time this weekend and was planning on de-rusting and using rustoleum to paint the edges of my front rotors where they're gotten fairly rusty... I've never seen this done, but it seems like it shouldn't be too hard... Any advice on possible trouble I could run into with this? Thanks!

The discs get extremely hot as in red hot. The paint won't last, even high temp paint would be challenged.

I wouldn't go as far to say they might warp...I'd just give those discs a good cleaning.

Callipers... yes. Rotors?... nope.

ahh well good thing i asked before making a big mistake... howabout the other part where it gets rusty around the bolts? And as for cleaning do you recommend scotchbrite?

If/When I have to remove the front rotors on my Vibe, I will use some emery cloth to remove the surface rust from the hub and coat the hub with some Anti-Seize (be carefull not to get that stuff on the rotor surface). So if their is a next time when I have to remove the rotors, they'll come of without the use of a "Persuader"

I have always used rustolem on my brakes calipers and the edge of the rotors, I originally got the idea from my neighbor who is the biggest car guy I have ever known. I have never had a problem with heat, the paint last for years. I will never understand why people pay up to $40 for the high temp paint.

Just to make sure I was making myself clear to the other guys who posted near the beginning, I wasn't talking about painting the silver face of the rotor, but the rusty metal that goes around the sides. Seems like this part isn't directly used in the braking process and therefor wouldn't get so hot..? You guys know way better than I do though Thanks for all the help!

I've painted rotors (not the brake surface) on several cars to cover up and prevent more rust. I can't stand to have some nice alloy wheels on a car that show nasty rusted calipers and brake rotors. The heat actually bakes the rustoleum on. Spraying the cleaned rotor with a little brake cleaner/degreaser will help the paint stick. I brush paint the rotors and calipers to keep the paint off places it shouldn't go. Masking tape helps too.And if your rotors get red hot, you got a problem!

I've heard how hot disks get and calipers get and you need high temp paint.Not so,I've painted my rotor edges and the paint doesn't burn off.It gets abrasion and abuse esp. over winter.I personally use Tremclad brand (Canadian tire), and have used Rustoleum.Hi temp not required. Nothing wrong with hight temp, and won't hurt - but not necessary.
