POR-15® is a high-tech, high performance
rust-preventive coating designed for application directly on rusted or seasoned
metal surfaces. It dries to an incredible rock-hard, non-porous finish that
won't chip, crack, or peel, and it prevents rust from recurring by protecting
metal from further exposure to moisture. Use it to coat rusty frames, floor
pans, farm equipment, marine equipment, or even a heavily corroded battery tray.
Available in 4oz, pint, quart, and gallon sizes.
The secret lies in the POR-15® curing
process. Unlike "paint", POR-15® cures by drawing
moisture from the atmosphere. Paint, on the other hand, cures through the
process of solvent evaporation through pores (that's why you can smell a paint
job for weeks). Those same pores allow microscopic amounts of air and moisture
to gradually reach the surface of the painted metal. As you know, if ordinary
paint goes unwaxed for very long, rust will form right thru it! But POR-15®
doesn't have those pores, and thus moisture and oxygen cannot reach the metal
surface, and therefore no rust can occur.
POR-15® is sensitive to UV light (sun)
and must be top coated for prolonged exposure to sunlight.
Top coating is not required for areas not exposed to sunlight.
