TECTYL 121B BLACK UNDERCOATING APPROVED UNDER FEDERAL SPECIFICATION TT-C-520B

Tectyl 121B Black Undercoating, is a premium coating blended with asphalt, wax, and mineral spirits. It is a premium rust preventive, chip resistant, and sound dampening undercoating.

The cured film provides a resilient matte black finish that is firm and flexible. This powerfully stable and conforming base layer allows for additional coats to be applied without the fear of peeling or cracking.
