TE Wedge Attachment

Has anyone ever used J.B. Weld for attaching the Trailing Edge Wedge instead of using Pro Seal? Which one works better for this application?

Are these the elevator wedges? If so I would use sealant, it will be lighter since it spreads more evenly and you will use less. The sealant will also flex and will not have a tendancy to disbond if/when the skins flex.
