AB I think for part of one yearís production didnít use some kind of primer that they use to glue the tubes to the hulls, and got very early failures, I mean while they were still in warranty I believe.
There is a dealer in SW Fl that sells both AB and Highfield and maybe others, I should have bought from him and didnít, but he will talk to you and I bet tell you exactly what kind of adhesive
and what prep work etc is required.
Sorry donít remember his name, but I believe heís the only one so it shouldnít be hard to find.
Iíve heard of people using 5200 to patch dinghies, but I believe there are better products
