When stick and tin has to be repaired they remove some siding and do the wood repair. When they have to repair laminate they have to replace entire wall sections.
Walk into any campground, USA and look at the laminated trailers. Especially the ones who are 5 plus years old. It's not uncommon for these trailers to have what looks like big blisters on the front of the trailers, many times on the back and around the windows. This is delamination. It could be water intrusion, it could simply be that the fiberglass has let go of the substrait.
IMHO this is a major reason why we see one piece fiberglass caps now. Fiberglass caps hold up very well aesthetically speaking.
For me, I prefer sticks and tin. But really if you have wall damage from a leak its a bad situation with either build method. Sticks and tin is easier for an experienced DIYer to repair at home. I have never read about an effective home brewed solution to delamination.
