I doubt it is true epoxy as it is one part, and it states it adheres to metal, but I am trying it this year. Got it at a big box - not marine graded, obviously. Epoxied some dings on the rudder blade with West System and the white structural filler powder, washed with soapy water, then sanded it and cleaned with fiberglass cleaning solvent. The spray goes on well and is glossy, after 2 coats. We'll see if it survives a summer under fresh water.
I tried Interlux epoxy barrier coat (white) in the past and was not happy - went on too thick and hard to brush out (too tacky) and it is a pain to dole out the proportions.
