Great for a fully paint stripped car

I'm working on a '40 Ford at home, in my attached garage. I do not have the facility or equipment to shoot today's good-but-dangerous urethanes and epoxies. It'll be acrylic lacquer. For prep, I stripped all the old paint to bare steel. While a lacquer primer is usually OK on steel, with the acreage I had to cover, it seemed a metal etch primer was cheap insurance. It was easy - no mixing, shoots as is out of the can. Easy to control (I used an HVLP gun), and the mild acid in this product had no effect on the few nooks and crannies where old paint remained. It'll be while before I get subsequent painting done (hi-build primer, sealer and topcoat), but meanwhile I have rust protection. Considering the job I threw at this product, it performed very well.
