UNDERCOAT is a unique spray which undercoats, deadens sound, prevents rust and seals most surfaces. UNDERCOAT provides a durable, flexible, rubberized film which seals and acoustically reduces unwanted vibration and sound. UNDERCOAT protects metal parts against the harmful effects of water, salt, battery acids and most other chemicals. UNDERCOAT stays pliable in the winter cold, yet will not sag, melt or drip in the heat of summer. UNDERCOAT resists cracking, peeling and abrasion.
