Okay, I did a boil test on a sample of the Okume 1/2" and the 1/2" ACX Radiata plywood. After 30 minutes, I was able to pull apart the Okume while the ACX maintained its integrity.
Question- does standard exterior grade plywood delaminate after a boil test? The price on the non-marine Okume sure looks good but, am I wasting my money if I use it?
