This Corroless and POR15, is that like a rust converter/inhibitor.
We have stuff here called Rusist, it converts the rust to whatever rust converts to, thinish milky colour then goes purple when it goes over the rust, stays milky over good metal, not deep rust, more like surface type rust. Normally I would sand off surface rust, but for the spots I can't get to.................., then could I paint rubberizing over that or would I have to put a rust preventative on first. Will have to do Ruby's underbelly one of these days, so may as well get all the info now.
