Product Description

Auto Tech Rust Prep
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. Unique formula is two products-in-one: it kills or 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! Converts to a zinc-phosphate coating, resulting in superior anti-corrosion and welding conductivity. Speeds up production. Easy spray, brush or roll on.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!

How It Works
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.

Due to Hazmat regulations, lubricants/fluids cannot be shipped to APO/FPO addresses.

I have used this product so much this is my third bottle. This you just spray on the rust (knock off the chunks) and let it dry, it will turn white and physically changes the surface to a phosphate coating which is great for paint. I sprayed this all over the place on my 1967 Dodge Coronet during restoration and so far have had no issues with any place I have painted.

The price is right here too! I paid over twenty dollars in a parts store for the same bottle.

Yes, I would recommend this item to a friend!

Product arrived with a label that was placed over top the instructions on the bottle, so that was extremely annoying, i carefully tried to peel it away but it removed the application instructions. BE EXTREMELY CAREFUL NOT TO GET THIS ON YOUR CARS PAINT!!!! IT WILL EAT TROUGH THE CLEAR AND PAINT DOWN TO THE METAL IF NOT WIPED AWAY. I had some slight over-spray and ruined my cars 27 year old original paint in a couple areas.

Yes, I would recommend this item to a friend!

I believe this the best rust stopper there is because it stops rust and is also a metal conditioner so you do not have to use a self-etching primer on top. It is also works very quickly. You can be ready to prime or paint within an hour, whereas you have to wait 24 hours for other rust stoppers to work and they are not metal conditioners, but only turn the rust into primer.

Yes, I would recommend this item to a friend!
