I have a SuperStar 40 Select as well. This is what I did. I simply bolted the wings together first with out gluing anything. It flew fine. I could do loops rolls, etc. Then once I flew it awhile, I found it to have around 8 deg's of diheidral(sp?). I unbolted the wings and took out the steel rod and bent it to around 7 deg's. slipped it back in then I had a flat bottom wing with 1 deg dihiedral. It flew quit different. I did this only to get me ready to go to an ugly stick type of plane.
If your bound and determined to "glue" the wings together, my own opinion would be to use epoxy or gorrilla glue and put it on one end of rod and slide it into one end of the wing, then glue the wings together. Make sure you get the epoxy/gorrilla down inside of the holes where the steel rod goes in on BOTH sides. The joint where the wings meet is important as well, DONT skimp on the epoxy here. It is better to wipe the excess of with alcohol and a rag than to not get enough in this joint.
As far as the fiberglass tape, I've used it once on a HOB Super Decathlon. What everyone at my field told me to use was THIN CA on it. I did and then monocoted over it and it turnd out really good, although I only used it on the bottom.
I would suggest just blting the wings together. If you insist, go ahead and epoxy as well. But skip the whole fiberglass tape thing. Just remember the lighter your aircraft the better you will be. If its as heavy as a rock it will fly like one.
Just my $.02, hope it helps
