Is the original message from Chris or Joe? 1.8 dacron over the plywood??? I don't get it. Wouldn't you still have to seal and prime the plywood? Moisture could trap between dacron and plywood otherwise developing rot. And doesn't dacron require several coats of nitrate then several coats of silver UV protection and then finally several coats of butyrate just to assure a life span of a dozen years??? Nine to twelve coats of finish is about what the process is, which seems to me to be far more difficult than dealing direct with ply or a single layer of glass cloth.
