The finish colour was Will's idea
I knew it could be done , and we did it on a tester first
But I rejected a lot of tries to get it right before I was happy we had it right
I just wanted a certain amount of transparency/opaqueness - which we got right in the end
I drove my paint guys mad in the meantime

It's the main reason it took most of this year to perfect the technique.
Thanks so much to Will for his patience - hope the final result is worth it.
