Where can I find marine grade plywood

[coombro]

Lowe's info, if not in store they will order for you to pickup there.

15/32 x 4 x 8 Marine ABX PlywoodItem #: 12344 | Model #: LBR12344
$57.28

Be careful about the treated wood, because the stuff its treated with can cause galvanic corsion long term, and its hardderd to get marine adhesives for carpet to stick to it.

Treated plwood sheet =
4ft x 8ft x 1/2in Fir CDX Treated PlywoodItem #: 202760 | Model #: 202760 $24.97
Eitehr way, good luck man.

You work at Lowes? Just wondering as you had all that info.
