Hey Gang, hows the flying season going? I hate being busy during mine...

Question; My Sig Riser had a slight mishap last summer and I'm in the process of repairing it. I bought it at an auction so I didn't realize this before, but the "wing tips," the part of the wings with the dihederal, are not permanently affixed to the wings! The had a dowel in the back and a tube in the main wing that a metal rod from the tip fit into. The previous owner used tape to hold the wing pieces together, color matched to the covering. Its about an inch wide. Does anyone know what kind of tape this is? Thanks
