I will attempt to recall my Coal-Tar Epoxy experience from four decades ago, which is at times, at my age, is easier than to recall four hours ago...lol: It was recommended to me by a friend who did underground tank installations. I had no prior knowledge of the product. I don't recall the manufacturer, but it wasn't one of the popular paint companies. It was a marine grade product. I applied by spray using a Binks #7 gun. A pressure feed gun may have been a better choice, as I wasn't able to get much of a pattern. As stated, metal was freshly sand blasted. I applied per manufacturers instruction of no primer...direct to metal. I don't recall any softness to the coating once cured...actually very hard. I can attest to it's hardness as I got some in my hair which the only solution was the cutting out of some clumps. Over time the rich black color did turn more of a dark gray (Hot Rod) primer color, but protection was never compromised. It took a number of years for the color to fade, as any 'paint' would in time. If appearance is a concern, a top coat of enamel or urethane could be applied.Thanks grover26! Can you attest to it never hardening and staying black? Did you prime at all?
