Hmmmm.... I just finished doing a UCoat-it floor on my new garage a couple of weeks ago, but I'm pretty sure I don't understand enough about the chemistry in the bonding process to give anything other than a random answer. So here's my random answer - I'd do a second thin coat using the remainder of the bonding stuff (Part C) mixed in with the Parts A & B. Then continue with what the instructions call the second coat (the top coat) per the instructions. If you're not doing the gloss clear coat on top, maybe call UCoat-it on Monday & see if they'd recommend it as kind of a sealer in your situation. I put it on (the AF coat) and it definitely made the floor tougher, although the AF stuff is a b**ch to put on. It's solvent based, so you've got to turn out the pilot lights in your furnace and water heater. I ended up doing the AF coat on a fairly warm day & the pot life of the epoxy I found to be shorter than the instructions said - I had to work like a MF to get it all down before it started turning to glue. All that said, two weeks later it seems to be as hard as rock.
