Go ahead and acetone wash, and grind back the areas that would trap moisture.
I would set up a two 250W brooder bulbs inside the anchor
locker, and tarp it over so no dew or rain can find its way in.
Keep the plywood
hotter than a hundred degrees, but where you can still hold your hand against it without being burned.
In a 2-3 days... Tape a piece of plastic sheet over the top of the board, and take away the lights.
If you still have condensation
form on the plastic, it isn't quite dry enough to glass.
When you can tape down the plastic and have no condensation
you are good to go.
Use clean everything with Acetone. Grind everything with 36 grit. Use Epoxy. Mix a little thickened epoxy and fill any holes in the corners. Wet the plywood
with resin. Lay three layers of 1708 biax, one at a time into place and call it good. Wet out the first layer, use the next layer to mop up the excess epoxy.
If you weigh your fabric
, you'll use the same number of fluid ounces to wet out the fabric
, as the fabric weighs.
Air roll the fabric with a bubble popper. Only extend up the side of the hull
3 inches or so on all corners.
If this is your first job, I would roll on some excess resin and try to fill the weave without leaving puddles. Come back and grind/sand until you just see cloth and then wait a few weeks... Paint
with Interlux Bilge
Tape, and plastic cover the deck
so you don't get epoxy prints on your gel coat. Even if you wipe up well with acetone, you'll still have some yellowing if it gets on the gel coat... So, cover everything!
