Is this product available in black?

Thank you for your question. The answer is no. Loctite Extend Rust Neutralizer Spray is only available in clear. It converts rust to a neutral surface ready for painting.

No it is clear, but if done right it will turn steel rust black. As for time give it a day to dry for 2 reasons, one it is water based and two the chemical phosphoric acid needs time to react. Don't get in a hurry for best results. I use this product all the time. Finish with Acrylic or enamel paint to seal it from moisture/water, a must! Think for it as a primer that will need a top coat.

Why would you want it in black? It turns black all by itself which is how you know when to add the 2nd coat.
