Would you guys agree on the use of one-part polyurethane adhesive
instead of two-part epoxy with filler for gluing several (4) pieces of
1" teak wood planks in order to make a properly shaped base between the
windlass and the deck?

Thank you in advance

I used a polyurethane one part ( "Gorilla" type) glue to make a tiller
handle. It brags about being the strongest, but says it's unsuited to
immersion. I was unhappy that it foamed out on finished surfaces,
looking very untidy during the setting interval. This is also a reason
why it calls for a light clamping force - else it can spring joints.

Over time it will absrb moisture which can cause the bond to fail.
So if you use this kind of glue, makes sure you have a good heavy
varnish finish.

That's the beauty of using epoxy - the bond is a lot more impervious to
moisture although it will still need the varnish finish to protect from
UV.

Six of one - etc...

I originally built parts of my MiniCup sailboats with "Gorilla Glue"
and I wish I had not. It has poor gap filling properties and seems o
let go after prolonged immersion. I have had to go back and replace
it with epoxy.
