Septone Brush-On Seam Sealer is a fast drying brushable sealant applied over exposed seams and joints which have been welded, riveted or bolted. It is designed to produce a permanent, flexible seal with excellent adhesion to bare or painted surfaces and no sagging, and duplicates O.E.M. appearance. It prevents corrosion-causing moisture, dirt and sludge from being trapped in voids or crevices or between overlapping metal. Use it to seal seams in floor pans, fire walls, boots wheel wells and utility trays.
