Try to PM Buck Garza (yeahbaby). I don't know what he did, but I saw his Kingcat at waco a couple weeks ago, and I saw fiberglass all over the midpart of the boom. I didn't ask whether it was a repair or a reinforcement, it looked more like a repair, but I didn't get close enough to really tell. I just saw what looked like a fiberglass tape wrap approximately 18 inches wide.

Good Luck,

Sean
