Karetaker - It is in perfect condition. 3 years & counting. I originally thought the edge would unravel, but it is sticking there with no signs of un-doing.
My forward fiberglass W/Shield fairing is wrapped too. It was a lay up / pop it off to finish up edges / rivet & proseal type fairing, I was also able to vinyl wrap with that the same technique. I laid a very fine fillet of proseal along the w/shield edges thought & hose edges are holding up great too.
Poindexter - my suggestion would be to fashion either an aluminum or fiberglass Targa Strip, than either paint or vinyl wrap it. Vinyl alone will not cover the crack (will show right thru it), also vinyl won't be adding any strength to the broken area. I would proseal the leading edge to the plexi though like I did the w/shield.
built a few RVs, rebuilt a few more, hot rodded more, & maintained/updated a big bunch more
