It's not actually Avcoat.
It was changed by LM.
Thw honeycomb was removed.
Imagine a beehive with no honeycomb and a slop of honey is what you have. Crystallized/solid honey, but honey never the less.
It is still Avcoat, that's just the name for the epoxy+silica 'honey.' But yeah they got rid of the honeycomb structure due to labour to manually fill the cells costing too much. Seems like kind of a dumb place to draw a line with the budget considering all the overruns it already has, means that now the Avcoat is being used in a design it wasn't originally meant for
