Well the reality is that surface tension dynamics really ARE weird stuff.

It is very hard to know what you are doing and what is happening just from
these posts.

I think I mentioned before how my brother gave me darkroom equipment, long ago, and I tried
to learn how to print photos and was having problems. We talked for hours on the phone
trying to figure out what I was doing wrong and finally found out I was putting the emulsion
side of the paper down instead of up. Of course if he had been there he would have seen the problem
immediately.

I'm not suggesting you're making such a basic mistake, only that it is really difficult to know
what's happening through a post. If we could be there and see what you mean, obviously it would
be much easier.

Back to surface tension. I would suggest you go over the surface with a foam brush and really push
the resin against the previous coat.

I do have times where a new coat or resin, over a green coat, wants to not break the surface tension.

I roll all my resin on. The roller makes air bubbles or foam in all but the wet-out of the glass layer.
I take this as a given and routinely go over this surface to "tip off' or break the bubbles. AS I do this,
I also use the brush to smooth out the new resin, push it into spots where the surface tension is
resisting and to smooth drips and runs.

I think if you apply some pressure with a brush in those trouble spots it will help.

All the best,
