Outdoor Furniture

[Gibbcutter]

I am reupholstering exterior furniture. Under the existing fabric is plywood. Because of the age and delamination I cannot tell what plywood was previously used. Any suggestions as to what type of plywood I should get?

As it is outside I would use MDO, paint it before you cover it. Or marine grade plywood

Either may be overkill, but one and done makes sense to me
