View attachment 170014 Disagree all you want but POR-15 is low quality and anyone knowledgeable that sees that stuff on a car immediately knows there are problems underneath being painted over. It’s an expensive ‘backyard mechanic’ way to convince yourself that you’re stopping the rust.
Anyone that applies it to clean bare metal is not only wasting their time and money but they are guaranteeing product failure as it needs the rust to attempt its so-called “bond”.
Marine clean, Metal ready, brushed, diluted/sprayed.... doesn’t matter. It’s trash. I’m trying to warn folks before they find out the hard way- been there, done that.
