Re: plywood type for fiberglass .
Wasn't clear where this is and its purpose but the minimum grade you should use is a ply with exterior glue ac bc exterior are reasonably resistant to exposure and most importantly have few serious voids
cdx is not remotely ok as.current products have been known to delaminate onsite while waiting to be used! Polyester is fine for this then prime and paint or use pigment from the beginning
