ONLY MIX WHAT YOU NEED EACH TIME, once it's mixed it has a life of about 15/20 mins max then it has to be discarded.

Is it possible to pre-mix your 2 pack gloss clearcoat then keep it in a jar for later use if not all used in one go, or is it a case of just mixing enough to do the job?

NO YOU MUST NOT DO THIS, once you mix the clear coat and hardener a chemical reaction is started, similar to epoxy glue or epoxy putty. It will hardened within 15/20 mins, if you mixed the lot you would be wasting product and money, so only mix whet you need each time, you will quickly find the amounts you need with a small amount of practice. 
We would recommend starting with 10ml/gram or Clearcoat - 5ml/gram Hardener and 3ml of Thinners and see how much coverage you get wer fin this is plenty to clearcoat a 1:24 model with 3/4 coats.
