Guys,
Am getting to the point of seating the wing in the fuse and there are some small gaps to fill. In the past I would use some small scraps of wood and just glue it in. Is there anything stronger and easier?

I certainly agree - nothing works better than balsa glued in place.

Just recently stumbled across a new product (new to me anyway) made by J B Weld. Called Kwik Wood.  Its a putty you mix with your fingers like chewing gum.You then work it anywhere.  It would remind you of Epoxolite-only thicker.  Ready to sand in 30 minutes.  Its tough and not too heavy for smaller jobs.  Get it at the Home Depot.

Seams around wing to fuse are certainly places where you want decent strength - and a little flex.

In the past i've used epoxy with chopped carbon fiber. You can alter the consistency with how much carbon you add. Can be thin or quite thick and paste like.

Just make sure you wipe off any excess to avoid sanding it too much - it will sand but not as well as superfil. Depending on how much gap you have, small gaps superfil is perfect. If you have anything more than a 1/16 gap I'd try to fill it with Balsa first or the epoxy.

I get best results with 15 min. epoxy with lots of "micro balloons" mixed in.  Add a bit of acetone for smooth application.
