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.
Review: Rust prevention - Works good.seals rust.saves time less grinding and buffing.

## Features

- Black Star Rust Converter – No more sanding, blasting, scraping, or etching. Instead, our 21st century technology converts and transforms rust into a slick polymer resin coating. A phenomenal rust treatment, Black Star rust converter stops more rust from forming.
- Won’t Re-Rust – After converting your rust into a beautiful, black, hard, corrosion-resistant polymer resin that seals out moisture, the treated rust will never reoxidize. Instead of being just a harsh rust remover, Black Star is also a rust inhibitor and chemically reacts with the rust to convert it into a useful primer or final coating.
- Unlimited uses – If it rusts, Black Star goes to work! Used everywhere from oil rigs to farm equipment. From fences, metal roofs, bridges, marine applications and steel sheds to grain bins, cars, trucks, trailers, and tools, rust is simply no match.
- Paint primer – Rust is difficult to paint over, and paint won’t stop your metal from re-rusting. Black Star not only acts as a rust converter and stopper, but also is a phenomenal primer for painting your metal and achieving a vivid, smooth color.
- Easy to Use – No more difficult rust removing! Instead of damaging the metal trying to remove rust, just spray, brush, or roll on Black Star Rust Converter and improve the integrity of your metal without worrying about stripping, wire wheeling, grinding or sand blasting.
