temporary wax for waxless skis when all stores are closed?

Thanks everyone for all the replies. I'll check out all these
suggestions. I didn't end up even trying to ski today - way to busy
since I was cooking Christmas Dinner anyhow.

I saw that the one place that sells downhill ski stuff here is having
a free clinic early in Jan on Ski maintenance including waxing them -
I think I'll try to attend that - even though it's downhill skis
probably it'll probably still be relevant.
