Replacing Rotten Wood in Cabin Top

rebel heart · 16-03-2009, 17:59

Cross layed plywood (30+ years), painted over. I've got a patch that's about 24" in diameter rotted fairly bad. No sunlight shining through, but one hammer blow could probably bust right through the thing. The real rot is a 12" diameter center. It's on the cabin top, and it looks like the offending leak has been fixed before. It's just dry rotted out at this point.

I used CPS just to try it out, and was thinking that I might just build the area up with some West + 307 fairing filler, smooth it out, repaint, and be done with it. Maybe put in a piece of cloth to add some strength, epoxy that in, then add the thicker epoxy compound, sand, and paint.

I'm a little spooked about cutting the wood out and replacing a 24" hole; maybe it's just psychological but it's freaking me out either way.

Does the epoxy repair sound legit, or chicken $h|+ ?

If I get a piece of plywood, would I "marine treat it" somehow?
