Now... for new material. What do we like? (No, Lew, NOT mahogany marine

Time for some 3/4" CDX plywood, and epoxy thickened with micro-balloons.

Use the thickened epoxy to fill and repair surface defects in the CDX
(Both Sides).

All bolt holes get drilled oversize, then filled with thickened epoxy
and finally thru drilled for bolt after curing.

As a example, for a 1/4" bolt, drill a 3/4" hole thru ply, then fill
with epoxy. When cured, drill a 5/16" hole thru epoxy.

Seal with a good oil based primer followed by finish of choice.

Good for at least 10 years, even in Sarnia.
