Product Details

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.

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.

Bottom Line Yes, I would recommend to a friend

Appears to be working
By Paul from Sayvile Long Island

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.

Bottom Line Yes, I would recommend to a friend

Sorry, this one is a bust
By Unhappy Customer from NW Indiana

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...

White chalky coating makes a ton more work

Great stuff!
By Diver guy from Richmond

Used this on several tools, but where it really worked great was on my old rusty truck rims. Sprayed it on in the afternoon and let it sit overnight. Then sprayed the rims a second time and they look like new. Bought a small plastic spray bottle from the Dollar store to use as a dispenser.

Bottom Line Yes, I would recommend to a friend
