What got me thinking about the fiberglass and the firewall was reading about the Hanger9 Corsair.

I only have a 40 sized trainer and I did run a small bead of epoxy along the back of the firewall were it meets the plywood sides.

I had never heard of finishing resin before coming to this forum and now I know I can use the finishing resin for fuel proofing and for laying down fiberglass cloth.

One question is how do you go about fiberglassing the back of the firewall if the plane is an ARF - just seems like a mess to me.
I know I don't need to fiberglass the firewall in the trainer but I would really like to know how poeple are pulling this off.
