To mate the trailing edge skins to the center strip, I mixed a few ounces of ProSeal to act as an adhesive. ProSeal is usually used to seal fuel systems, but also works well to mate these surfaces. WIth all holes aligned, I cleco'd the two electric wire channels to each side, giving the trailing edge a solid and straight template for curing. It will cure in 3 days, whence we'll come back to clean up a bit and start a very tender rivet job.
About ProSeal: It is absolutely nasty! I forgot to get acetone for clean-up, but then remembered my Dad's WD-40 lesson....it'll clean anything!
