Your link doesn't work, at least for me. I've used the red zinc based primer on frames and such in the past, but I'm not sure if it will work on a body. I imagine it would if you thin it enough to run in a sprayer. You'll have a lot of sanding after though, but you'll have that with any body paint job you'd do (depending on how much you care about the final results). $10 a gallon is a good deal.
