clear finish - crystal clear requirement - wiping varnish base

i am after a poly that is as clear s possible - most of the poly i have used has a honey cast to it and generally darkens and yellows things slightly -

water base is not applicable as i want to use it as a base for wiping varnish



i would be happy to use water base but gargling wb wiping varnish brings up many results saying that adding water will destroy the chemical properties of it and prevent it cross linking properly



2 pack would not be applicable for this application



bit of an icky little corner this but hopefully some one will have some sage advice
