Exterior Fiberglass Bulging Gary 12-30-02  
I have a 1987 Komfort 31 foot class A, it's a fiberglass model, and the sides are bulging in different places, I suspect from water getting in between. I have some different ideas on how to try to fix it. One would be, drill a hole in the bulge area, and pump some kind of glue in, unknown glue? Than try with my mechanical ability to patch the hole with fiberglass. A mechanic and fiberglass, ya right, I would be better off Duct taping it. The other idea would be, is to try to open the bad area's at the seam's, pore glue in, again unknown kind of glue. The last thing I thought about doing would be to get long strips of 1 inch by 1/8 inch metal, and try to hit the metal framing in the walls, where ever possible, and screw it to the sides. I found out after buying this M/H that Komfort got the heck sued out of them for this exact problem, that's why they don't make them anymore. They where literally flying apart going down the road.
Any idea's or suggestion's would be Greatly Appreciated.

I have heard of a company that does just that. They drill a small hole in the affected area, then glue is blown into the hole, and then it is vacuumed out pulling the delaminated part back to the base material. Maybe somebody else can get you in touch with them. Over a year ago when I was talking to a person at Coachman that had worked for Sportscoach, he told me about somebody that was doing that. The problem is that I lost the phone number for that company doing this type of repair. Sorry that isn't much help, but there is hope.

De-lamination has been a major night mare for many manufactures of RVs. I have see plenty. Can be caused by water leaks, and of course the pounding it takes going down the road.

I doubt you can hit metal ribs with screws, cause there usually are very few, and they are only around windows etc. There may be a permanent solution in re-gluing, but I have not seen it. The manufactures I have talked to suggest replacing the entire wall panel, and you can guess what that would cost.

The way I have repaired these is with a double headed screws called a hex bolt. It has a screw head on each end, and screws into its self, like the screw fasteners in some note book binders. You can usually get these from local fastener supplier. Or go to, and to a search for hex bolt. They come in brass, stainless, aluminum, and a variety of length and diameters etc.

I usually try to space them in some sort of pattern if there is many spots, and paint the heads to match the exterior. I suppose glue could be added to strengthen the joint too.

Thank You Joe!
That's something to think about. I never would of thought about using a Vacuum Pump. I can get a hold of one. I'll give it a try, as soom as it warms up a little here.
Thank's Again Joe.
