Hello - I have a 1989 Cruise Master by Georgie Boy. I need to replace a piece of siding on the coach. It appears to be fiberglass because I can see fibers in the siding. But, it almost looks corrugated. I can't find any reference to this kind of siding on RVs. I sanded an ugly brown stripe off the side of the coach and never met metal - I've attached a pic that I hope shows what we have. My question is: Is this siding available anymore? Does anyone have any idea where I can get it?? We love this old beast and just want to fix her up. Any help would be appreciated! Another question - is this type of siding glued on? Or? We are trying to figure out how to make this repair look good.
