Rust Treatment, 1 Qt Btl, Opaque

It seems to convert the rust and leave a rubbery like, black coating on the steel. So far I like it and what it does. The first bottle this size (1-quart), lasted through a 67 Cutlass, 71 C10 stepside muscle truck and 77 GMC truck. Besides the normal brushing on, I tried to use it to fill a cavity.... Dont bother unless you can tip that item in all kinds of angles to get it to coat. By filling a cavity, it just creates a film that turns black where exposed to air and under it, it will still be liquid. I tried to fill the rear cab brace on a square body GMC. After waiting 2 weeks for it to harden, I more or less gave up and just moved on with my project, spraying it down with coal tar epoxy. I attached 2 pics, the first showing the raw steel framework for the sail panel (C pillar) for a 67 Cutlass after I sanded it down. I coated the sail panel framework with this stuff before buttoning it up with a donor rear quarter. It works OK if you put it in a squirt bottle to reach tight spots. Just dont put in much. As for the bottle, brush, paint cup or whatever you use to apply this, itll be ruined. Im not even sure it can be cleaned from a brush well enough to matter, I just buy the 99 cent brushes (not foam) wherever I find them and toss when Im done. The lids for aerosol paint cans or a Dixie cup work good as a holding cup. Do NOT put unused product back in the bottle! A little goes a LONG way... Imagine brushing on water and how well thatd cover if all you had to do was get the surface wet. This stuff is bad news if you burn it and has a weird smell. Yeah, youd never intentionally hit this with a flame, but if you coat the inside of the panel with this, then weld that panel in place..... Make sure its well ventilated, dont need a third arm popping out of your back mid project. Wait, that might actually be useful, my luck Id get a third ear that doesnt work any better than the other two useless ears, but itll be on my forehead.... Dont do it... Dont let your young body write checks your old man body cant cash... Lastly, Im part of several large car groups and it seems that all the other products out there that do this similar thing with rust, arent any better than this brand. A couple are close to equal, but many fall short of this stuff.

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!

Treated my rusty Toyota Tacoma truck frame with this product. Followed by a spray can primer and spray black paint. It is holding up well and has seemed to slow the spread of the rust problem in the past 2 months. I would recommend this to anyone who needs to slow the spread of rust on anything steel.

Wow! Great product, great price, great vendor = Great DEAL! Im impressed! Thanks!

Perfect met my expectations.

Wish it turned more black than opeq.

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.

Does nothing it claims. Bottle says: - Destroys Rust - Seals & Protects Metal - Dries to a tough protective primer coating OK, it might dry to a tough coating, but I used this on some lightly rusted sheet metal AFTER I thoroughly removed all visible rust with a wire wheel. Then applied this product. A few weeks later all the rusted areas were rusting again. Look elsewhere.

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.

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