Which LPS should you buy?
One goes on thin and dry. One goes on thick and waxy. Choose accordingly.
LPS Laboratories numbers its products, and the two we review sit at opposite ends. LPS 1 is a greaseless lubricant that leaves a thin dry film for electronics and precision instruments. LPS 3 is a heavy-duty rust inhibitor that leaves a thick, waxy film for storage and outdoor equipment.
Neither is a penetrant. If something is already seized, free it first with a dedicated penetrating oil, then reach for LPS.

LPS questions
What is the difference between LPS 1 and LPS 3?
LPS 1 lubricates with a thin dry film and is meant for precision parts. LPS 3 protects against rust with a thick waxy film and is meant for tools and equipment in storage. One reduces friction, the other blocks corrosion.
Is LPS 3 good for rust protection?
It made our best rust protection list. For saltwater exposure or undercoating, compare it with Fluid Film, Boeshield T-9 and CorrosionX on that list.
