TotalBoat Rust Primer converts rust and prepares metals to be primed and painted. Use it on new metal for superior paint adhesion. Its unique, phosphoric acid-based formula is thin for easy application and excellent coverage of over 500 sq ft per gallon. Use it on just about any metal in high moisture, high humidity environments. It's perfect for marine engines and trailers.
TotalBoat Rust Primer is incredibly easy to use: First, use a wire brush to remove accumulated dirt, grease, loose paint and large rust flakes. Then brush the primer on. The metal will turn black to indicate the chemical change. Let dry. Simply brush off any dried residue and the surface will be ready for primer.
Available in Quart and Gallon sizes.

Sprayed the entire underneath of my 1977 Jimmy that's being restored, before undercoating. It did wonders on the rust on the frame and everywhere else. I just used a 16.00 insecticide sprayer from Lowes and it worked great.

I covered a 2000 sq ft metal rusty roof with this stuff it worked as it said it would, I coated some portions and wasn't able to put a roof coating over it for days and the rust has not even begun to come back with just primer on it. This stuff is great

I sanded all rust with a DA sander on the top of my 24 ft car hauler. Then put rust stop primer in a regular hand spray bottle and applied that way. Soaked it on good in the shade and let it sit all day. All steel is black. Next step is primer then EPDM rubber coating.

I am repairing an old trailer, with a lot of rust, using this product first and it works like a charm.

I have only just used the product on some rusted items, followed by metal primer and several coats of paint, so won't be for a couple of years to see how this treated materials hold up to some others I painted before getting the rust primer.

Applied to two different frames side by side. One came out perfect, turned black and is ready for paint. The other one, the rustier of the two, dried with a chalky white powder all over it. The chalky powder will rub off on your hand but will not remove completely, it shows thru primer when I tried a spot. Does not remove with air or acetone. Outside for a pressure wash is next. Really, REALLY unhappy with this product. It made a nightmare of additional work. Never again for me...
