Testing Popular Rust Encapsulating Paints

Rust Encapsulating Paints

The Repair Geek YouTube Channel performs comprehensive testing of rust-encapsulating paints. The meticulous investigation features a lineup of renowned brands, including POR 15, KBS, Eastwood Rust Encapsulator Platinum, Bill Hirsch Miracle Paint, Rustoleum Oil-Based Enamel, Raptor Liner, and Mastercoat.

Rust Encapsulating Paint Testing Criteria

The Repair Geek thoroughly examines six crucial categories: adhesion, chip resistance, flexibility, UV resistance, corrosion resistance, and chemical resistance. The testing process unfolds over eight months, allowing each paint to undergo essential UV exposure and, in some instances, pushed to failure within a salt fog cabinet.

Contrary to prevailing internet opinions, the Repair Geek aims to challenge the status quo by revealing that there are superior paints on the market compared to the widely praised POR15. The goal is to empower viewers with the knowledge needed to make informed decisions when selecting the perfect paint for their specific projects.
