Replying to Sticky skins trouble

Bought a pair of Montana skins during the 2018/2019 season and used them a handful of times. My first time using them during the 2019/2020 season I had the hardest time pulling them apart at the trailhead (stickier than I’ve ever dealt with). After transitioning at the top, my skis wouldn’t slide due to sticking to the snow assumingely from the skin glue on the bases. Thankfully my buddy had some sort of wax that I slabbed on the bases which somewhat helped.

My question is are these skins trashed? What should I do? recommendations for wax?

since these are fairly new skins, I really don’t want to buy new ones. Help!
