Rubber membrane sealing tape like for roofing or window installation. Sticky as heck, bends and shrinks, small rodent proof. Want airfoil, stick it with hinge point on outside, want smooth, stick on flat side of hinge.

Julian Edgar was doing things with increased radii corners, not necessarily an airfoil although he did use a gawd awful Gottengen profile windmill blade (mostly because he could get them easy/cheap)
