I can't see it helping. Any coating you put onto the face of the rotor will be worn away immediately & they're typically very rusty in the areas that don't matter.
If you want to do it for "looks", sure. Clean with some good carburetor cleaner/brake cleaner to remove the shipping oil (you do this anyway on the rotor faces), tape off the faces, use spray paint on the non-face part (probably better use hi-temp engine paint) & wipe off any excess that got onto the faces with more carb/brake cleaner.

Well if your rear rotors now are rusty where the pads hit you really have a problem , probably the calipers are stuck. I didn't know that the brake and clutch fluid were in the same reservoir. Are they? And as for the ceramic pads, If you think 60,000 miles is to short of a life span, ceramic will destroy your rotors in half that mileage. Better stopping , but most of the stopping power is on the front brakes.

Yes, on these cars the clutch master uses the brake master cylinder reservoir for its fluid. Sometimes when I get in the car in the morning to leave for work after it rained overnight, when I release the parking brake, the pads are "stuck" to the rotor and break loose as I start to move. I used to have a '95 Ram 1500 where the front pads would "stick" to the rotors after the truck had sat in my driveway a few days. You could see faint pad shaped marks on the rotor when you looked at it. I'd go through front brakes like crazy on that truck, every 10,000-12,000 miles they'd be shot. I also had a 90 T Bird SC 5 speed at the time and I got 135,000 miles on a set of front pads on it, so I don't think it was my driving style that wore out the Rams brakes so quick. I worked at Raybestos then and fortunately got an employee discount on parts, Rotors and loaded calipers were around $90. I got pretty good at replacing that trucks front brakes! Finally I got the idea of replacing the front metallic pads with ceramic, so they would not rust together and stick. That idea worked, my Rams brakes no longer were shot after 10-12,000 miles. That is why I am thinking of using ceramic pads on the rear of my Dart.

not worth it if its a daily driver, rotors will only last 2 years till they warp or just wear out with grooves..no one cuts rotors anymore..just saying My rotors and brake drums are chromed on the 71 cuda, no worst for wear, but then it only drives in nice weather...they have been chromed since 1985

..no one cuts rotors anymore..just saying FALSE.I have had 2 sets of rotors for both the front and the rear of my 2007 Ram 1500. When the truck starts to get brake shimmy, I swap in the pair I have on the shelf. I have had all 8 resurfaced twice and they are all still over the minimum thickness. I have 308,000 miles on this truck and have driven a LOT of commute miles. Find a decent shop that is willing to surface only enough to "true" up the rotor and be a baller.

Find a decent shop that is willing to surface only enough to "true" up the rotor and be a baller. i guess i'm the only other one on the planet that cuts them. i have several aluminum "plugs" i fabbed that fit several size center register bores. i first blast the hubs inside and out with steel shot. i then blast between the cooling fins. then, i coat the blasted surfaces with whatever color of high temp, or "quality" paint i have laying around. after the paint dries, i set up the "plug" in the lathe, bolt on the rotor, then cut the bare minimum needed to true the surface, one side at a time. usually, only .003-.008 total material need removed, and runout is only .0005-.001 when finished on my lathe. rotors last a long time and many, many miles. and yes, i have two pair of rotors for my daily driver[s], so i just swap 'em out, then cut the extras at my leisure. time consuming ? yes. economical ? depends if you have to buy medicine and pay doctors and hospitals all the time. i have to stretch every dollar as far as i can. plus, it keeps my machinist skills up to date, and me out of trouble. i also realize every person does not have the equipment, nor the desire to take the time to do this, plus the fact finding a parts store that does this any more is just about non existent.
