The next thing I tackled was the formed cap-over bunk. All the way around the bunk there was OSB sandwiched between a layer of fiberglas. The two ends(L&R) had the OSB completely rotted away, and a small corner in the front(nose section) had some rot. I cut and fitted new 3/8" marine grade plywood into the bottom portion on the bunk unit.
I poke and scraped all the rotted wood from the ends and poke and scraped and drilled the corner area to get to good wood.

To repair the above corner, I poured some Rust oleom's wood preservative http://www.rustoleum.com/product-catalog/consumer-brands/wolman/woodlife-classic/ along the ragged edge of the OSB deep in the corner.
After that I mixed up some fiberglas resin and poured it so the exposed edge inside the corner was coated. I don't know if this was necessary but the area does support that section of the bunk.
The last thing I did was pump the poly adhesive between the fiberglas sheets. I just kind of piled it in there. I had previously cut a piece of 3/8" marine grade plywood to fit into the corner. I coated the adhesive quite liberally onto the plywood and shoved it into the slot. I took a short 2x4 and kept tapping the plywood deeper. I knew I was settling up to the adhesive when it began to ooze out. When it wouldn't go any further, I put a 2x6 on the top and one one the botton of the fiberglass and clamped them down tight to form a new sandwich.


I will then trim the plywood flush with the fiberglas edges.
Here is how I was able to pour into the corner...
