Thought I would p*** this on. Just used Ch***is Saver paint on the bottom of the cab of my '55 GMC. Worked great and i saved like $50 (gal. price) I have used both POR-15 and Eastwoods Rust Encapsulator and this stuff measures up just as good if not better. Wire brushed everything cab bottom, bed fenders etc. and gave it 2 coats. Looks slick. I bought this stuff thru my local tru-value hardware. Oh yeah, takes about a week to come off of skin. Kent
