yeah looks like delam, especially the 'end' of that section
who mounted the bindings?
they go deep enough on drill/screw depth?
not familiar with the ski/cosmetic - these metal topsheet? if so, were the drill holes tapped and countersunk appropriate to materials?
is there visible cratering under the binding mount?
heavy cratering can pull up/relieve the topsheet from what it's glued to... and start the delam process.
if they were properly mounted then it should be a non-brainer on factory replacement - which can be a glacially slow process
you got another pr to ski on?
