The most recent WB has a scary sidebar about catastrophic failure of supposedly marine grade plywood. I recently took delivery of $1100 worth of plywood and I am wondering how I can test it before putting it into my current opus. The stuff I got is from Homestead Hardwoods in Ohio and is described as BS1088 Hydrotek Meranti Marine Plywood. It has no Lloyd's stamp, and has a dragon logo which might imply an Asian supplier. The WB sidebar describes delamination when exposed to sun: Is there a recommended protocol for testing? Should I soak it in water and leave it out in the sun for a couple days? Help!
