We used the Invisible, and that is self sealing so it did not require a sealer. we first tried 2k Supra satin on a few boards but did not like the color change and it was too shiney.. I wanted as natural as possible. Nothing will be completely clear, but the Invisible comes pretty close! I love my live sawn white oak. we've been in the house for a few months and it is simply gorgeous. Huge west facing windows and no glare at all. I would call the Loba headquarters in North Carolina for absolute correct advise on the Supra. Good luck!!
