Yes. It's so simple and silly at the same time. Water doesn't effect it. It can withstand temps of over 275-300 degrees, and if you do it correctly, gives a uniform tough finish. The only thing I have to do is remove the crankarms from the rings, mask off the Dura-Ace writing on each arm with perfectly cut electrical tape and then sand/scuff them in a uniform manner so that the "medium" I use soaks into the porous metal(actually the most time consuming part of the process) with a good 400 grit sandpaper. Then I "paint" them (well not really), put a few coats on, air dry, carefully remove the electrical tape then stick the parts in a pre-heated oven and bake at 275 degrees for 4-5 minutes.... WAH-LA. You now have beautiful, OEM looking satin black "Dura-Ace" crank arms!!!! The satin finish will show off the "machining" grains of your sanding, so it's important to know how to sand the metal uniformly.
