It will probably need another paint in a few years, but I’m happy with that. I strip the callipers down every winter, so to give them a quick rub down and another few coats is no big deal every few years.
The original powder coat was the best finish, so I may get them powder coated one year when I have other bits to do, like the bash plate which I whacked the other day on a nice rock. But, for a little effort it’s good to know the brakes can look like new for not a lot of money.
