PEN Penetrating Oil penetrates, frees, and cleans all hard-to-get-to places as the aerosol pressure forces this lubricating oil into rusty parts and gives better, faster penetration. Loosens rusted nuts, bolts, and studs commonly found on mufflers, tailpipe fittings, brake cables, lock mechanisms, speedometers, and carburetors. Unique spray valve system allows application from any angle...even upside-down.
CONTAINS TEFLON®
PEN always leaves a smooth, slick surface. The special formula contains Teflon®, which is one of the most slippery substances known.
POWERFUL CAPILLARY ACTION
Pen contains a unique combination of ingredients that permit rapid, deep penetration of corroded parts.
MOLECULAR ATTRACTION TO METAL
Pen has an affinity for metal, which aids penetration.
LUBRICATES AND PRESERVES
Pen leaves a residual oil film that lubricates and provides protection against subsequent corrosion.
