Rated 4.2 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by AWESOME STUFF I've been using this stuff now for a few years. I use it to cover welds on 2" galvanized pipes, fabbed into radio antenna towers. The pipes are close to the beach in a semi-marine environment. Because I nor my customers don't want to pay for such large pieces getting hot dipped galvanized, I use the cold spray approach and save money. Although this cold galvanizing is NOT as tough as true hot dipped galvanized, but who cares? This stuff works so much better than using regular primer coat, followed up by paint. Because this cold galvanizing compound is primarly 93% zinc, I've found that it outlasts all paints and primers. One word of advice however: MAKE SURE YOU SHAKE THE CAN FOR ABOUT 5 MINUTES!!! Then continue to shake it in between spray applications. The stuff is really thick with zinc while in the can itself. You really want to mix the zinc well before spraying it on metal surfaces. Just use this stuff like you would a primer coating. Follow up with a top coat if you so desire. I only rated its "value" with 4 stars because like everything, it could be a little less expensive.

Rated 5.0 out of 5.0 by WORK GREAT IN WATER (anti fouling paint) This works great as an anti-fouling paint on props, shafts,trim tabs and drives. Plus you get the extra zinc protection. Tried it last year and going to get some right now. April 6, 2013
Rated 5.0 out of 5.0 by Great product Used on my above ground pool walls that had rust. Applied after removing rust and before putting a new pool liner. Easy to spray onto walls, and looked great. I strongly recommend a mask! Fumes are strong. Use a fan while spraying it so fumes dissipate. All in all a great product ! May 8, 2014
Rated 5.0 out of 5.0 by decent product I prefer to treat any rust after scale removal with Ospho and spray with this paint after 24 hours and this will last for many years, especially on any farm equipment that is continually in use as in hay balers and combines. Better than hot dip galvanizing and if any wears away, spray some more over that spot, but that happens infrequently. Ospho converts the rust oxide to a calcium based product that does not progress further. I haven`t found anything better. Shake often... June 9, 2014
Rated 1.0 out of 5.0 by Scratches easily If you expect a hard (galvanizing) finish, buy something else. It scratches easily and does not provide a hard finish. After spending an afternoon wire bushing and cleaning a galvanized steal bracket, the application went on nicely and it looked great. The next day, it was easy to scraped off the paint with my fingernail. I followed the directions, at room temperature and a clean surface. Results were very disappointing. October 12, 2013
