So this week, at the suggestion of a friend, I rented a power-washer to remove the old flaky anti-foul coat. Doing so revealed what I believe to be gelcoat voids. There is absolutely no wetness, toxic / stinky fluids. I have revealed hundreds of them and fibers of what I believe to be the skin-up mat behind. I've decided to stop the power-washing for the moment, thinking perhaps I am causing more of a pain for myself than necessary…
I am curious of your thoughts on a couple of options:
Should I continue to power-wash
and reveal all the “loose” voids and then repair? My thought here is to go ahead and get it over with.
Should I just scrape (by hand)
the rest of the anti-foul coat off, sand, epoxy fill the current crop of voids, sand again, probably barrier coat (might as well, since there is some sort of void problem) and then anti-foul-coat, then sail.

If you don’t mind looking closely at the last pic in the album, you will find “bubbles” that haven’t been removed. These are what makes me wonder if this is a sign that I should continue removing all the “bubbles” as some look to have hairline fractures on their edge that I wonder, if in time, will allow water inside, causing future damage. Or will a solid couple of coats of barrier (Interlux2000e) take care of it?
Finally, to those who have done epoxy filling under a boat -on a trailer- do you have recommendations as to how to make this process quick but effective? Don’t worry about the safety advice, I am very familiar with nasty chems and metals and take over-the-top precautions.
