Review: Great product, works fast, leaves great finish - Searched for rust stopper products and found this had great reviews. Bought the quart bottle to see if it was all it says, it is. It brushed on easily. I poured out small quantities into a cup and painted the various rust spots on a deck over trailer I am rebuilding. I painted the major spots at the front of the trailer and the metal plates on the deck over the wheels. I was pleased with how quickly it went after the rust spots, turing black and when dry it seems to be a good sealed surface. I then applied a quick coat of spray paint. I still have to scrape and paint the axles once I get the brakes replaced. I wire brushed the brake drums and repainted them as well. I plan to buy another quart and the spray version to get at some places that a brush can't. This is a great product and I highly recommend it.
