Hi guys - I think the dimples are from surface contamination on the wood, its too late by the time you see them. Theory is to sand until the wood is clear and try again. Next time keep the wood as clean as food, and sand it before first use. My dimples were from errant wd-40 mist from a few feet away.

I didn't sand off the whole coat, I had so many dimples I would have had to. I did sand into the cured epoxy, just roughing it up, and recoat, the dimples were lessened, and after varnishing no one will ever know. The varnish is perfect. Well, almost perfect, you certainly can't see the dimples....

I would similarly not worry about mottling, and the rest of it, unless you are talking about cloudiness. The varnish goes on as thick as the epoxy and cures many sins...

Finally another plug for the slow cure epoxy , I use it and pot life is not an issue in my garage. It sets by the next day and then I resume boatbuilding.
