For any IML'er that is thinking of treating the rusty metal of their Imperial with POR-15, I would invite them to check out this website http://www.zerorust.com/. Though I haven't tried this stuff yet, on the underside of my 67, it comes HIGHLY recommended,and is supposedly much safer to use than POR-15. ZeroRust is actually supposed to out preformed POR-15 in a heads up test. Has anyone tried ,or heard of this stuff ? I remember reading that "Skinned Knuckles "restoration magazine tested and rated all rust converter products on the market. Did they rate this product?. Of course I have no affiliation ,or financial interest whatsoever in ZeroRust. Clay Smith 67 Crown Coupe
