Rust Treatment, 1 Qt Btl, Opaque

Great product for what I am working on.

We used this product in the paper manufacturing industry on rusted/ corroded internal components of process equipment. It reacts with (rust) to form a tough primer coating and cleans up with water. Extend performs well. It’s not “cheap” but worth the money. I had to have some at home so I found some on Amazon. I’m sure that other similar products are available, but I know that this product can withstand the harshest conditions.

This coating worked well on a metal roof, to stop rust, seal it, and permit re-painting. Also works to stop rust and seal a dishwasher rack, to prevent further rusting. Update: Two years later, no more rust!

works charms on old parts, stops rust, a must have for the workshop. price was within range for my expectation

arrived on time, Extend works great

This is a good product at a reasonable price. Easy to apply and as advertised converts rust to a stable platform that can be painted directly. I had a couple of rust pockets at the lower edge of a pickup truck, after applying this product I was completely comfortable that the rust was stabilized. I applied some Bondo over the area because some metal was missing. A great repair, in which I am confident will last for years.

works wonders

5 star product. Price was twice what i could buy it locally.This is why the 3 star rating.

Ive used this for years on rusty metal. Especially on cars. Ive tried others but keep going back to this. Got tired of paying ridiculous prices for a tiny bottle. Now I got one big bottle for the price of 2 or3 tiny bottles.

great product and speedy delivery
