RE: Any ideas on a super durable finish that will take a beating?

When people ask for a hard finish I go with post catalyzed Krystal Conversion varnish. It’s my go to these days. I’ve sprayed it on commercial and residential bars etc. Quite durable. On furniture I often wet sand it with 1200g-1500g after and it gives it a beautiful silky texture (and takes the sheen down some)
