Yes, thanks for the update, and congrats!

Process question, what did you do to prep the Coosa before laying it into the deck, any cleaning, or sanding? And same question for Coosa on the upperside, before starting to lay the top skin glass, what prep, ie. cleaning, and/or was there any sanding?

Really looks great, kudos to you, and glad you are back to sailing.

Re: Replacing wet balsa core

no just vacuum dust and wipe with acetone. If you sweat or dirt and oils get on it, you should wipe it with solvent. I found Coosa to be very similar to laying large tiles, or 1 big tile. what you do with mortar, you do with corebond.
