I have seen some jacks that have a rubber (polyeurothane?) pad on the end to protect the car. I have a Sears/Craftsman jack... anyone know if there are pads out there for jacks?

The Eastwood Company sells a rubber pad that replaces the metal dish on a floor jack. They also have a metal pad with a groove in it, that prevents damage to the projecting metal seams on the rocker panel.

If any place around you sells hoists and equipment you can buy hoist pads that will fit most floor jacks. They have rubber pads on them and are reasonably priced.
