Dry Film Lubricant - HM - 30:

Bearings are not the only part that will benefit from being coated with HM-30. Crankshafts, pistons, and other engine parts also perform better when coated. The HM-30 coating reduces friction, provides a more durable surface and reduces wear.

HM-30 is also used extensively on automotive fasteners and in many other commercial applications where reducing friction and/or a more durable surface is necessary.
