http://raybuck.com/i-66984-zero-rust-paint-quart-black.html Its looks good And WAY cheaper then POR15. I have already ordered POR15 but i have 2 cars to do.
I've not tried it but it looks interesting. Only complaints I had about POR15 were the cost and it wasn't a good primer for the NASON urethane paint I'm using Didn't really try to use POR15 as a primer, only in hidden areas, e.g, under the fenders. But, when some urethane got on the POR15, it wrinkled. This stuff is less expensive and its SAYS its a good primer. Worth a try. If you try it please post your results.
