I'm sure you all have at least seen the process mentioned before. I had and thought in this case it might be the right was to go about it. I found it to be very functional for this area. I now have a very strong bond and the gap was filled. I'm not sure why the gap was there in the first place. I test fitted that wing several times and reconfirmed alignment via panel lines several times before glueing. When the wing was cut for the Wolf Pack wing fold set, there were no alignment pins, not that makes a lot of difference, but it did make for a slow process of aligning the upper and lower inner wing halves. The Wolf Pack inner wing was then added and was quite a good fit with no filing or sanding needed to get in. this should not have affected the wing to fuselage mate but it seems like the upper wing is just a tad further in then the lower. the other wing fit with little issue. The alignment down the rest of the wing is as it should be for panel lines. Anyway it seems to have had the desired results of a strong bond and filling the gap. It also filled in the forward lower sing root with little sanding necessary. The moral of the story, try it you might like it. more pictures later.
