I've had no problem with teak bonding with epoxy. I precoat the bonding surface with un-thickened epoxy before adding thickened epoxy for the final bond. I don't know if the precoating was required, but it did work. I didn't clean with any solvents.

: rudder in case I want to install one in the future. I'm also planning on
: glassing teak rails on the inside of the hull to mount the footpegs. I
: chose teak because it's a hardwood that I think will be resistant to rot
: if it's epoxy encapsulation should eventually fail. Anyway, I know teak
: has some natural oils and I was wondering if any particular pretreatment
