Wow what a product I can't believe how great this is if properly used right then it works amazing I used it on my truck and it was pretty bad on my rockers and cab frame i sprayed and then brushed it in let it dry and wow it worked so good I'm happy I can get my truck lined out before it gets any worse and now I have zero worried I'm now basically rust free Thanks

Difficult to find small size. It lasts a long time and can be paintdr over without sanding.

Just order my second bottle. I wanted to test it first before purchasing the full amount.I am stripping a black metal fence. It is 14 years old and has several rust spots. I did use a wire brush on my angle grinder so knock off loose paint and to remove any lose rust. I am about halfway through the first bottle and I have done maybe 40 ft of fence so far. It seems to work very well. In fact the worse the rust was (within reason) the better the product performed. I have some areas very superficial rust. In these areas it did not turn completely black. In areas where the rust is more pronounced, it change the rust to a hard black coating.It goes on easily. I used a small paint pan and a 1 inch brush for my application. It is about the consistency of say Almond milk. It will drip, but it if you don't load up your brush too much I did not have much of a dripping problem. Time will tell how long it lasts, but my first impression is very good. I will come back and update this review should it's longer term performance be subpar.

Would have gotten 5 stars but I found the gallon jug at a different retailer for less $$$ then what I paid here... but this is an awesome product I highly recommend!

This takes 48 hours to cure. Then you can paint it.
