No you wouldn't feel cracked resin until or unless you open it up a bit. But I wasn't offering an opinion as much as giving you a way to know either way.
But if you've tightened the expander and the "crack" didn't expand, then you have your answer.
The advice is greatly appreciated. Tbh, I still find those jagged patterns super odd. I can't comprehend how a mold would have left this kind of imprint, and I really don't think it's a demarcation between two sheets as it would be straighter. Cracked resin is probably as bad as cracked carbon itself as it's part of the structural integrity.
