I have a small job replacing some mahogany bench style seats and some center console parts on a old Boston Whaler boat.  I have glue some panels together for the seats etc..  Is a Type II pva glue good enough, Poly glue, or is there something else I should be using.  There are no parts that will be in direct contact with water, although they will get wet and lots of sun.  The customer is going to finish the parts; marine spar varnish.

Thanks in advance
