fiberglass question

The coating is clear not paint but the fabric is not bonded to the wood. It came away easily in the sections that need repair but might be bonded in other parts where the wood grain is visible. Did Old Town sheath canoes in fiberglass or is this canvas with a clear varnish? I think I am reading...

I am re canvassing a 1995 Old Town OTCA. I recieved it partially stripped. Do I need to remove all old fiberglass epoxy and paint from hull? If I am re-canvassing does it matter if there is residual epoxy? I have removed sponsons, and there is no paint or fiberglass underneath. Not really sure...

Do I need to treat the cedar with a light coat of resin before I apply the fiberglass or can I just lay the glass on and start to apply the resin mix? The temp is falling and will be under 70 degrees F. even with the heater I have in my garage. Do I need to wait for spring or go for it? :(...
