What if surface is part rusted, rest painted? With spray can there will be some overspray. Will primer stick to enamel?

Surface rust--It depends on how deep the rust is. If really rusted I would use a wire sanding wheel attach to a drill and grind as must rust away as possible (wear goggles to protect eyes)and then sand... If just surface rust I would use fine grade sand paper to treat area. Clean area as best as you can and spray a few coat of red/black (your color choice of primer) primer on area and let dry. Yea, there will be some overspray but sometimes that can not be helped..... Primer stick to enamel. Yes. It depends on what type of paint is on item you want to spray. I would say yes that primer will stick to enamel. I don't know if companies still made enamel primer, some do and some don't. Read the label on the can. I would sand the area were you want to prime with a fine sandpaper to remove the shine from the enamel paint. Clean area and try a test area to see what happens.............Good luck. JMJ

Will this work on tin? I have a shed with a tin roof and I'd like to preserve it since it's rusting.

Well, I dont want to get your hope up but you can but how long is stays there is another question If the tin is really rusted and in sad shape I suggest you replace it but slightly rusted you may sand it lightly and apply 1 light coats of primer and let it dry completely and then give is a second coat...…..It may last a while but wont last for ever...……..The panel may be rusting from within itself and paint may cure the problem but it may still rust as time goes on.,.....

Can I use this on wrought iron outdoor table and chairs?

I have used it as a primer for wrought iron, followed by a color coat. Remove loose rust as much as possible.

Use on galvanized pipe?

No, this will not work on galvanized pipe, there is a special primer for that.

Useful and convenient

This is amazing and convenient. I used it to paint a truss bridge in my model train layout. It looks beautiful with homogeneous painting. Delivered in time.

High-Quality Rust Primer with Great Coverage

Rust-Oleum Stops Rust Rusty Metal Primer Spray is high-quality paint that works really well. The texture is smooth, it sprays evenly, and the coverage is excellent. The finish comes out nice and consistent, making it easy to use even on larger projects. Rust-Oleum offers a great variety of colors. I got the flat brown, and while it’s exactly the color of the cap, I thought it would look different on my project—it’s more of a reddish-brown than I expected. That said, it’s still a quality product and worth the money. Overall, I’m happy with how it performed.

Great primer spray paint

4th time i have purchased this. I love most all rust-oleum products, but this being a primer just knocked it out of the park on an old metal fence in serious need of repainting. Terrific product. Ease to use, no spray issues. Great coverage too.

Rustoleum it is...

Quality of the paint is extraordinary... Covers the rusted area completely... It also penetrates rusted surfaces thus bonding with the metal beneath the rust... Overall a quality product...
