Just my 2 cents, but I would not paint the firewall before installation, because I think you will possibly get a stronger and better adherance if the glue joint for the firewall joins a more porous non-painted surface.
Duane,
I had planned to leave bare spots for gluing. But painting the firewall is pretty mandatory, since I have pencil lines all over the front.
Cheers,
Richard
