I want to build a simple shower seat for my folks and was thinking of using either Teak or Ipe to build it. What is the best glue for these kinds of hardwoods? I've read to wipe the joints down with acetone or denatured alcohol to remove the oil and then use either Titebond III or Gorilla Glue. I also want to back up the joints with some kind of mechanical fastener and was thinking of using stainless pocket screws. Sorry, no design yet to show or post but doing my homework on how to join these kinds of materials in the most durable manner. Aloha.
