Re: Is Marine plywood a must?

The only difference between marine ply and grade A ply of the same wood is that marine ply has no voids and more ply layers. Neither of them are rot resistant or waterproof or anything "marine-ish". Your application doesn't require the bit of extra strength more ply layers provide, and any voids are inconsequential.

You should consider glueing the pieces together when you screw them in place. Thickened epoxy is good, but you could use a liberal amount of a premium construction adhesive too. Edge sealing is good also, although the paint will do some of this.

Glassing isn't necessary, but a layer on the outside carried over to the existing box would tie everything together nicely.
