1986 Gulfstream Sunsport 27ft rebuild

Hello all, Looking for some advice on a rebuild I am going to undertake. Well already started. I am working on a water damaged wall about 12 foot section. The exterior is that corrugated fiberglass with a Luna backing Foam then the la un lintier wall. Any one have any suggestion of Glue to reattached the Luna to the fiberglass then foam the the inferior Luna. I am also going to add some more wood on this wall as there was very little in there in the first place. The super structure is steam and has surface rust I'm going to clean as best I can and apply rustolium to it before reapplying the walls. Also it looks like the roof has damage as well and most in the front and the back area. there is also some sage in the roof. there are 2x4 place about every 6 to 7 feet I plan on removing the roof which is a thin layer of galvanized sheet covering a thin layer of Laun looks to be the same thinness as the wall Laun.. I am sure it is built the same way as the walls I do not want to remove the undamaged sections of the interior Celling so this is going to be a challenge. I so plan on recovering it with a slighy thicker La un and then applying EDPM to it and rolling it over the side about 2 inch as the side rails i am going to remove looks to allow about that much coverage. I know this is a lot and an ramble but any experienced advice would be great.

I have looked at many videos on line and many searches but there does not seem to be much on Foam wall fiberglass extierors.

Just as an FYI i picked this up for 750 bucks with 21K miles on it and it runs and shift and drives great. So i dont mind putting a few buck into it.
