I recently used MRO Chem Black Star Rust Converter on my truck frames, and I must say that it was worth every penny. Even though it’s more expensive than other rust converters, the results are impeccable.

I didn’t have to go through the hassle of sanding, blasting, scraping, or etching the rust. Instead, 21st-century technology converted the rust into a slick polymer resin coating that sealed out moisture and prevented further corrosion.

The treated rust will never reoxidize, and Black Star acted as a phenomenal primer for painting my truck frames. It was effortless to use – I sprayed, brushed, or rolled it on the structures and let it do its job.
