So JSP wanted some Pics.
I shaped a piece of Marine ply to fit in the bottom of the locker and bring the floor of it up above the water line.
On one side I bonded strips of woven mat and clear flow-coated over the top for protection.
The locker in original form.
This image also shows the anchor bracket in place that I fabricated as per this thread:-
The new floor in the locker with the already flow-coated side down, and the inside of the locker abraded where required.
The finished floor that Iím not that happy with.
Having run out of proper flow coat I mixed some wax into some lay-up resin along with the only colour I had, Yellow, which obviously produced a very thin flow-coat.
Itís gone off properly though, and as itís only in the bottom of the locker and will be covered with a rubber mat I donít suppose it matters that much.
Just need to add the drain now.
