new formula both kills & converts rust on contact and etches bare metal
A new twist to an old product! This fast acting formula kills rust on contact and converts it to a dry, paintable surface in 20-30 minutes, as opposed to the normal 8 - 12 hours required by other products. Also, this unique formula is actually two products-in-one: it kills/converts rust or, if sprayed on a bare rust-free panel, it etches the surface like a metal prep and creates the perfect surface for paint, primer or filler!
Rust-Prep works by reacting with rust to form a chemically inert ceramic-like strontium phosphate film that becomes part of the surface. When primed or coated, adhesion to the surface is increased because the zinc strontium phosphate film is cellular and actually creates a locking effect at the paint interface thus going way beyond ordinary adhesion. And the zinc phosphate film results in superior anti-corrosion and welding conductivity.
Rust-Prep prevents rust bleed through and also removes scales and corrosion from aluminum, galvanize, copper, stainless steel, fiberglass and wood. Rust-Prep dissolves lime and scales from pipes, evaporators, engine cooling systems, etc. and it bleaches rust stains from wood, vinyl, ceramic, porcelain, grout, glass, brick, cement etc. Rust-Prep has hundreds of uses - if rust or rust stains are the problem, Rust-Prep is the solution!
