Plastic dip works great on other end of tools, too
Coat the business end of your clamps with the plastic-dip material marketed to coat tool handles. It dries to a soft, flexible coating that will protect even finished wood. Apply it by dipping or brushing, taking care to keep it out of movable joints or threads. Coat the grip end of a pair of pliers or locking pliers, too, to make a handy tool for pulling out wooden axle pegs and the like.
