Ospho is phosphoric acid and it turn rust to black primer. I welded the sheetmetal in and cleaned everything with Under gone, basically a concentrated foamy citrus cleaner that supposed to clean up undercoating. Then I cleaned everything again with silicone/wax remover, then ospho, then one step rust killer. Today I will follow up with Eastwoods Rust Encapsulator then chassis black. I better not ever see rust on that floor pan again.
