Best technique for Hollis leaking seam

[Bald Wookie]

Don't get me wrong, I love Aquaseal. Some of my gloves and boots have ended up more aquaseal than neoprene. I'm thinking that if the OP starts picking around at the seem tape he's going to find more extensive tape repair is needed.

So @Bald Wookie, do you thin the aquaseal and "paint" the seam essentially?

Pretty much. Thin it out a little, put one thin coat on, let it thicken up, then apply a slightly thicker coat on top.

I'll add another preference, I find it hard to to patch jobs along seams with seam tape. There is always some overlap with the old tape and eventually the corners of the seam tape seem to start unsticking. Covering whole seams like when replacing boots/seals is much easier and has a better result in my experience.
