Cold Galv. Coating under paint

Okay so this is a product that we use at work and I recently saw on their website where a guy had restored a car using this stuff, so figured I would post it up and see what everyone thinks.

Here is the link.

I am thinking about getting some and using it on the underside of my 66 after I make all metal repair and blast it, but If it would provide additional protection under the paint and body work I wonder if it would be worth doing, and if it would be okay to use under whatever paint I was going to use

I use cold gal in the marine industry, also the inside of my torque boxes are coated in cold gal.
