I found ACX and Marine Grade at Menards. It's a bit out of my way, but I can't find it anywhere close. Think I'll get three sheets of the ACX. I cleaned the fuel cell today with Purple Power. I thought the thing was black, turns out more of a pale reddish color that was caked in black grease and grime. I'm doing small things on the boat, but I'm way off my original schedule, life happens. The new plan is to at least have it on the water this year for break in of the new engine. I'll take a weekend off here soon and do some more on the floor.
Good news is most of the stringers appear to be alright. I did some core drills that were dry and will have to maybe replace one full stringer if I can cut out the bad 3-4' and maybe sister one along side it. I will glass in the tops of all of them and I will at minimum put resin on the bottom of the deck.
Still not sure what to do about drainage though. I know some boats are sealed up and some are not. This one was supposed to have been and look where I am now. That makes me lean more towards draining everything back to the bilge. I have the idea of running a piece of 1" conduit through the existing foam in the bow that I am not working on to try and get a channel from the bow back. Not sure yet how to get the rest of the channels in and still pour foam after decking. I've seen some ideas around here and need to look again. Anyway, peace out and have a good one, this is going, but going slow.
