I know, I love that stuff, the results are great, it lasts a lot longer too.
only drawback is the cost, the local auto salon sells it for about $70 for a kit (enough to do all brake calipers/drums/hats & enough left for touch up work)
It's a three step system BTW, it comes with a can of brake cleaner, and the epoxy finish is in two parts, colored laquer and hardener, which must be mixed prior to application. it also helps to let the car sit overnight for the coating to cure up and harden properly.
BTW, it's exactly the same thing that companies like Baer, brembo and SSBC use on their calipers.
