Wow!!
I never realised there was such a huge amount of information and opinion about applying varnish! I was thinking of spraying as well, due to my neighbour being a paint technologist and having a degree in the subject and another friend having some spray gear. (But seriously, I think I will stick to a brush ) and I have now ordered some SP system UV stable epoxy on which I intend to apply a coat or two of varnish to finish
But thanks to all who have replied and shown interest.
