Engine dress and hose clamps?

If you want to dress up a standard hose clamps, think heat shrink tube. Just cut a piece to fit, heat shrink it on leaving enough of the slots open to tighten the clamp. Place the screw part of the clamp toward the bottom of the hose so it's not so visible.

Of course that doesn't help with the hoses, but it does help the clamp blend in with the hose.
