Seperation of outer fiberglass walls

My 1988 Royal Classc(class-c ) outside fiberglass thin sheeting is bubbling from the under walls ( I guess thin sheeting plywood).. Not sure what causes it , but I think it maybe the winter blues( cold weather )..Has other Rv'ers's had this problem?/.I'd like to glue it back on walls if possible..Or should I leave it alone?. Doesn't look that bad but you can still see it..Anyone tried reparing it them selves? How did it work out. ....John

Probably delamination caused by a water leak.

Some people have successfully glued the luan and fiberglass back. There are kits out there too.

I'm sure others will be along with more info.

I have bought West System 2 part apoxy resin from West Marine. I also purchased the West System syringes to inject the resin. I'm sure there are similar product other then West System but my maritime experience led me that direction.

I drilled small holes in a line top to bottom where the delamination was on the motorhome. I then mixed the 2 part epoxy and drew it into the syringe. I then injected the epoxy in each hole until to the best of my ability I had saturated the area affected. I then placed painters tape over the holes and used a brace to carefully brace the delaminated area to adhere and left it 24hrs before I removed the brace.

For me this worked. The downside is when done you have to then have to fill the holes and either paint or gel coat the area. But....it's all a waste if you do not first find and fix the leak.

Hope you get it all fixed as for a 1988 that looks to be in very good condition
