: Brand new here, building my first kayak, not much kayaking
: experience but a lot of woodworking. I love the look a tung oil
: finish gives to natural wood. I haven't seen anyone
: "finish" their boats prior to glass/epoxy. Are there
: adhesion issues using an oil-based finish? I'd like to give the
: entire boat a tung oil treatment, then glass and epoxy as
: normal.

: Thank you!

Hi Darel,
Any oil or wax on the wood will affect adhesion of the fibreglass resin, akin to trying to glue a piece of wood with the finish on it. That's why folks stick to alcohol based dyes for wood kayaks under fibreglass rather than using oil based stains.

You can expect a similar "wetted out" look with clear epoxy resin similar to what you get with an oil.
Enjoy your build!
Mark.
