I have a small amount of SP Ultravar resin and hardener. Both small tins are half full and the contents are still liquid but probably over 20 years old! Usable for a small repair job?
 
I used some resin the other day which must have been 10+ years old, and it set OK. Probably be fine for a non-critical repair.
 
I've used 20 year old epoxy and 3 year old polyester with no problem but have not tried old polyurethane,

It might be prudent to mix up a little trial batch to see how it behaves.

Plank
 
But what is it exactly ?

A quick Google only found SP Ultravar 2000 which is a UV resistant polyurethane varnish, but if its 20 years old it pre-dates Google.

Try it is all you can do apart from chucking it out
