I am planning on sealing the fuel tank bulkhead plywood on the 25 with vinylester, thinned with styrene monomer. After that I will glass it and tab it into the hull better, but it needs to wait a week or so, but I want the moisture resistance until then. My thought is to use a layer of peel ply, but I wasn't sure about peel ply over a thin layer of poly or vinylester resin if it is unwaxed, as the top layer doesn't fully cure? Any thoughts?

Thoughts that don't involve using epoxy, that is.
