Bought my first rib...question about tube material willard 7m

[dirtymike72]

I just picked up my first RIB, a willard 7M from the navy. It has Wing sponsons on it. I was told when I bought it that they were hypalon, but now I've been told by somebody else that since it has the WING sponsons, they're polyurethane. I have 2 pieces that need to be re-glued, and I'm assuming I need to know which material my tubes are so that I use the correct glue and procedure. Does anybdoy know how I can figure this out?

based on that, I appear to have poly. Thank you!

Wing never made poly. If you're really unsure, call them.

Are they grey or faded green?

Wing makes polyurethane, that’s their standard material?? They didn’t do hypalon until they partnered up with Henshaws?

Perhaps you were thinking PVC as the bad Poly?

I just went off what I was told, then on their website it says so as well. Maybe they were different in the past? That's why I'm asking so I can figure out what the correct glue to purchase will be

I'd say they're grey

Wing heat weld their tubes.. Henshaws use hypalon.

So I have this one piece that needs glued, what type of glue do I need to buy? I don't want to get the wrong stuff and risk hurting the tubes

Those are PU. I used to use the Clifton 2-part PVC glue.

You may have bonding problems. That material appears to be severely degraded.
