This is one of the times you need to differentiate "acrylic" from Polyresin and Alumilite.
"Acrylic" is manufactured under far greater pressure than the "home hobbyist" can produce. Hence, it will not have "bubbles". No CA is required, and I have never seen an advantage to using it.
With "home pressure pots" there is a possibility of bubbles in polyresin and alumilite. CA is a great way to hide and, actually heal these voids.
There is certainly room for differing opinions in this matter!!!
