Well....here is my 2 cents worth because I have been dancing around this issue since I started the restoration of C147. For me personally I think there are only two good options. And since I live where the sun does major damage to brightwork I'm going in the direction of the easiest to maintain. But sometimes I question myself and wonder if I would not be happier going with the best looking option.
Option one = the best looking option Epifanes varnish
Option two = the easier to maintain Cetol natural teak
