Delfleet is an excellent product. This product is very similar to the old Imron polyurethane products. Keep it off your skin and wear good mask... Instead of getting to worked up about the pressure at the comp. etc, paint your garbage can first. I use an old Sata Jet and typically go by sound and flow. I always paint something, usually it is my garbage can. I test the flow and how much I can apply prior to it sagging etc. HS is a high solids paint, I found that trying to lay down the traditional tack coat, then following up with two additional coats left me with much more orange peel, which is typical if premature evaporation of thinner occurs, or low air pressure at cap when using this product. I had much better results applying a heavy coat, then applying a second coat and cranked up the air until it flowed better. It does not flow like an acrylic or other single stage products such as Sikkens or thin as heck Dupont and waterbase coatings. it is a very good quality high solids paint, you can cut it by adding additional esx 520 as well, but I dont. I like this product but have heard much negative about it. I painted a 75 Land Cruiser and I used more pressure than 35 psi, I set my stuff at the recommended psi but struggled when I first started. The wetter you can get it just before it runs.. the better it lays down.. The Epox you are using is also an industrial coating typically used as a bare metal prep. It is not intended as a sanding primer, wet sanding works best to avoid clogging if you want to sand. A sanding primer is typically used after epoxy sealing for light filling and fairing. The Delfleet is an excellent choice as opposed to base / clear being the price of good paint has tripled in price as of recent, unless one is looking to achieve show quality finish. IMHO... Years ago I used a lot of Imron which was also a high solids paint and grew to like it much more than acrylics and synthetics. It is much cheaper than base / clear two stage and strong as heck. We use to paint our double bottom semis. Stone hits to the fibreglass would actually dent the surface, acrylic would flake right off as would lacquer. Take your time and experiment prior to painting is what I would try. Also, the day I picked up a trouble light and started painting while holding a light to see the "flip" was the day the jobs started coming around. Good luck to you!
