As the title say really.
Some say that CD50 is the bees knees.
Others swear by Sikkens yet I have also heard some swear at it.

I realise I need to leave this deck to bleed a while, then clean it before applying anything.

It's the "anything" I'm not sure of - didn't spend all this money making a deck to have it look bad in a year or two.

Any advice from people in the know?
