1) when I have my stringers all glassed in should I add wax to my last coat of poly so it cures properly? 2) do I have to sand thought all the gel coat where I'm tabbing the floor to the deck? 3) I watched a few videos completely removing the deck cap and cutting and removing the back portion of the deck and re-glassing it back in.. Either way it looks like a lot of work... Any suggestions or thoughts?
