Elaboration:
Only a fool or misunderstanding beginner would would use ca on plastic, unless it's it is to stick it together, it has not purpose in the finishing, polish is fine having been abraded to a high gloss.
ca on wood is the best finish we have available for a quick hardwearing, long lasting shine.
There are arguments against that but I will narrow them down to Health reasons and laziness and see what that stirs comment wise.
