Rust-Oleum 285011 Stops Rust Universal Watercolor Bonding Primer, 12 oz, White

My application was to restore Rohn 25 tower sections. They were stored for 12 years, and although never in the weather, there was some small rust spots, mainly in joints or cross-members. After cleaning and degreasing the metal I applied Rust-Oleum 330491 bonding primer.Kudos to Rust-Oleum Product Support Rep, "Karen", for recommending this product. The job turned out perfect and after the sections were painted the job came out better than I thought! I also used this product to paint several fiberglass communications antennas which were showing their age. The primer and paint did not affect the performance of the antenna, and again, another perfect job. I'm very satisfied with the product support and quality.

This is by far the best Rustoleum product I've ever used. It sticks to everything I've tried -- bare metal, painted metal, wood, particle board, melamine, plastic -- you name it. It levels well, it covers well, and it works well as a primer (preparing a surface for paint). It dries to the touch in an hour and the best part is (unlike all the other Rustoleum paints and primers I've used) you can TOPCOAT ANYTIME. (Other products require you to topcoat within an hour or wait 24 (and even 48) hours before top-coating -- woe to any painter who tries to recoat within the prohibited window. Having to wait that long before top-coating means that even small paint projects can drag out into days and even weeks.)The only downsides to this primer are:* It's more expensive than similar products* A can doesn't go far (Rustoleum says it will cover 10 sq. ft. but that's not much and I'm sure they mean a flat continuous surface, not a 3D one)* It's hard to find. Stores don't stock it because there's not much demand for it. There's not much demand for it because people don't know about it.* It's extremely smelly and should be used outdoors or in a very well-ventilated space. Be sure to use a mask. I used it in my basement with the door closed. and afterward I could smell it on both the first and second floor.Rustoleum intended this primer for difficult-to-paint surfaces, but I now use it for other projects (when I can get it) because of the fast recoat time.Note: You can also get this in a 1-quart (32 oz.) can, which may be more economical because spraying can waste a lot of paint. Both the spray and the brushable versions come in white and gray.

this is good stuff at a good price.

i Absoulty love the product it doesn't take much of this to make metallic paint stick and bond to this for an awesome finish

We primed heavy gauge stainless steel successfully. 2 coats of this, 2 coats black, and all good

Lives up to the high quality one expects from Rust-Oleum.

Love how I can use this to spray nails and screws to protect from corrosion and rust, since I live at the coast.

This is by far the best spray paint white primer.It is VERY EASY to apply and dries quickly. You can recoat ANYTIME without having to follow strict rules. It is the only primer that creates such a fantastic bond between the surface and top coat. It even works great on fiberglass. I build hobbiest model flying rockets. The fiberglass tubes take a licking without damage because of this primer.
