I have a fiberglass exterior door that I am getting ready to install. I need to install some jamb extensions provided by the manufacturer. Both the wood jamb and extensions have a primer finish. Their directions say to attach it with galvanized finish nails.
Instead, I was thinking of using some carpenter's glue and some finish nails from my nailer. I would putty over the nails and paint.
Is my method ok? Will the glue still hold with the primer finish? The door is underneath a porch roof and never receives rain.
