Around my house we do everything ourselves so we have tried a lot of paints ranging from rather cheap to fairly expensive. The Rust-oleum paints are my favorite for painting metals. We do demolition derbies all summer long and paint about 6-10 cars every year. We have used other brands of paint to make the designs and pictures on the cars and have had major problems. In the past we have had to completely start over on our cars because we tried using cheap paints. I have tried exterior paints that specifically said were for use on metals and nothing has ever come close to the Rust-oleum brand. I have had a ton of paints bubble up or peel right off the cars but that has never happened with this stuff. It goes on thick and in most cases doesn't require a second coat. I bought the other brands to save money and because I was scared of using the oil based paints and it ended up being a headache and cost more money in the long run. When painting cars or anything that will be exposed to the weather I will always use Rust-oleum because there is no other brand that can come close. It really does stop rust and works great. I highly recommend this paint to anyone who needs to paint things that will be outside and to stop rust. We have used it on a crazy amount of things around our house and have yet to be unhappy with it. I find a little goes a very long way also. Its definitely worth the money and I will continue to buy and use it as long as it is avaliable. I have bought the different colors they have and keep them in my garage in case a project comes along that I need it for. Everyone who paints themselves should have this stuff on hand because there really is so many uses for it. It goes on smooth and looks really nice when it dries and offers good protection against the elements. None of our stuff has rusted through or faded so I'm 100% happy with all of my results.
