Easy to apply by brush or spray, it covers 10-15 sq ft per coat and creates a paint-ready enamel finish compatible with body filler and fiberglass.

## Description

Permatex Rust Treatment destroys old rust and prevents new rust in one step. Just brush or spray on and within minutes rust is replaced by a durable black polymer coating, which can be painted and serves as an excellent protective primer. Specially formulated to be used with body filler and fiberglass, this rust treatment can be used in temperatures between 50°F and 90°F (10°C and 32°C) and on surfaces which do not exceed 200°F (93°C). Destroys rust on all automotive applications, trucks, trailers, storage tanks pipes, valves, fences, bulkheads, overheads, decks, hatch covers (topcoat with appropriate marine paint), agricultural equipment, plows, tractors, and snow removal equipment. Not recommended for automotive exterior sheet metal repairs.

Review: Stops Rust in Its Tracks - Stops Rust in Its Tracks I’ve used several rust converters over the years, and the Permatex 81773 Rust Treatment stands out for its simplicity and effectiveness. The 16 oz. bottle is a good size for multiple small projects, and the liquid goes on easily with a brush or spray. It’s thin enough to penetrate rough surfaces yet not so watery that it runs everywhere. On an old lawn tool and a couple of car parts, I applied it directly over rusty metal after brushing off loose flakes. The treatment dries to a black protective coating that seals the rust and leaves a paintable surface. It doesn’t just cover rust—it neutralizes it, which is key if you want your repair to last. Once cured, it’s much easier to topcoat with paint than sanding back to bare metal. The odor is noticeable but not overpowering, so I’d still suggest good ventilation if you’re using it indoors. Dry time is fairly quick; within a few hours I could handle the treated parts. The finish is a bit uneven if brushed on too thick, so thin coats work best. Bottom line: A reliable, easy-to-use rust converter that turns flaky surfaces into a solid base for painting or long-term protection. Great value for automotive, tools, or household metal projects.
Review: Works as advertized, primer & paint topcoat friendly. - This rust converter works as advertized. I had a 40 year old replacement hood that had been painted by the factory with lacquer and had not withstood the test of time after being parked outside in the weather & sun for 40 years. The hood was covered with surface rust so a very quick sanding followed by painting it with this created a primer & paint-ready finish. Just remember if you brush it on it WILL leave brush strokes you'll have to sand off or make sure there are no brush marks in applying it.

### ⭐⭐⭐⭐⭐ Have patience and follow the directions. This stuff will really work for you
*by J***2 on June 24, 2025*

Great product. But mostly if you follow instructions closely. I'm ordering a new bottle for the mower decks on my tractors. I used this product three years ago to keep the 20-year-old replacement floor pans in my '89 F150 from rusting through. This has been a little miracle for me. Make sure you prepare the surface properly and use plenty of ventilation. I recently pulled the carpet and the pads of my truck to reapply, and the floors were still 90% rust free. I wire brushed them, removed any loose stuff on the surface and gave them a new spray making sure to hit all the hard to reach places. Make sure the cabin of your vehicle doesn't leak because wet carpets and pads are a sure fire way to rust out your floor pans.
