I am finishing up my Great Planes Cherokee, and was wondering if I should get some of the 1/4" wide foam tape to seal the saddle where the wings mount under the fuelage. The reason I am asking, is because I hear this particular plane gets very slimy on the bottom, and I didn't want the fuel to damage the balsa in this area.

Is the foam gasket more trouble than it is worth causing alignment issues given the fact that this is my second plan and it will more than likely not be around long enough for the fuel to damage the wood anyway??
