Prevost XLII Skin Delamination Repair

[CC_Guy]

The re-glue process was Prevost's first fix. According to some, that approach failed, at least it did on some number of repairs. Then came the rivet approach that also required a change in adhesive. As I understand it, this approach too has failed. I don't know what the number of failures where after either fix and whether they were the result of workmanship in the repairs or actual failures of the adhesive or were do to some other issue. These could be isolated cases that can be explained. I just don't know, so I only throw this out as information I've heard.

With the advancements in adhesives and the fact that similar bonding has been done in other industries, it's hard to understand why this failure has occurred and why it has affected several model years. To suggest why the failures have occurred would simply be speculation on my part. What I find disturbing is that I have never heard of a single XL-II owner ever being notified by Prevost or their converter that they should have their coach tested for delamination. Not notifying owners, if that is in fact true, has to be a move now regretted. Unexpected failures or other defects happen. How you handle them is critical. Touting a million mile chassis and not notifying owners with far less than a million miles has to have a negative effect on new sales and certainly resale.

BTW, Prevost initially tested glued on panels with the passenger door on late model XLs. I've never heard of a single one of them failing (knock on wood). So, adhesives can work.
