I have been using Evercoat's Super Build 4:1. It builds like crazy - almost like spraying liquid filler. When you stir this stuff up for the first time you will get a feel for what I am saying. It seems the bottom third of the can is solids that you need to get mixed up into the liquid. Takes 10mins of stirring to get it mixed thoroughly. You need a really large nozzle to spray it effectively. I purchased a cheapo gravity feed gun with a 2.4 nozzle that I use just for spraying this primer. It is catalyzed. So once it cures, it's done and does not shrink back. I have found Amazon has about the best pricing.

I always lay down epoxy first, especially on bare metal. I have been using SPI's epoxy lately and it works great, especially considering the price point.
