Blackening the clamp.....
Hey Creek - I just read your posting that was in the link. To blacken the hose clamp on my snorkel I first painted the entire clamp with Rustoleum textured black paint, and then slid a piece of heat shrink tubing over the clamp, leaving just enough space to tighten down. Shrank the tubing down, then mounted it up, with the screw portion around on the backside of the snorkel where it wouldnt get hit by stuff and have the paint knocked off. Almost a year later, so far, so good.
