Autosel 2-in-1 Rust Converter & Metal Primer, Black, Heat-Resistant
Product description
Some rust projects call for separate treatment and priming, others benefit from combining those steps. Autosel brings rust conversion and metal priming together in one black coating for a more streamlined approach to treating metal.
Apply it directly over rust on automotive, marine, industrial, or other metal surfaces. The formula transforms rust into a hard, paintable surface while sealing out air and moisture.

Use it by brush or spray, with two to three thin coats recommended. Its water-based formula is easy to clean up with water, and the coating is designed for indoor and outdoor use.
How to use it



Stir the liquid thoroughly before applying it directly to a rusty metal surface. It can be brushed or sprayed on, and the recommended approach is to apply two to three thin coats without diluting the formula. Because the converter also functions as a metal primer, it combines treatment and priming in one application process rather than requiring a separate primer.
For a practical project, this can suit metal parts on a car, trailer, tool, or piece of machinery that need a rust-treatment coating. The product is also intended for marine and industrial metal surfaces. Allow two to four hours for the coating to dry to the touch and up to 24 hours to fully cure before planning the next stage of the job.

Why it’s worth it
The combined converter-and-primer format is useful when the goal is to treat rust and prepare the metal with one coating instead of sourcing separate rust treatment and primer products. Its black finish gives treated surfaces a consistent appearance, while resistance to heat, UV exposure, and chemical corrosion makes it suitable for metal used in automotive, marine, and industrial settings. Water cleanup is a practical benefit for application tools and work areas.

Buyers often describe the coating as easy to brush on and appreciate its coverage and flat-looking finish. Feedback on rust resistance is mixed: some report that it works effectively, while others mention rust returning. Those differing experiences make preparation and careful application important parts of the job, follow the product’s directions, including stirring well and applying thin coats.
