How to glue wood batons to inside boat walls and ceilings of a fibreglass type finish.

I am a lady who has a narrow boat (1970's), with a "fibreglass" superstructure, about 5 mm thick and that flexes. Originally it had a foam backed vinyl lining covering the surfaces.
This, from age and deterioration has peeled away leaving the old original glue on the surface, which is impossible to remove.
I desperately need to insulate and line the walls and ceiling areas, by adding wooden batons to surface, then pack insulation in between batons, cover that all over  with lightweight, plastic type tongue and groove sheeting. using small screws to attach it to the batons.
Seems simple enough?
But the wood batons will not stick to the bare fibreglass?? 
If batons are stuck on top of the old glue, the batons pull the old glue off so wont stick anyway, that seems to be the only way to bring the old glue off? 
I have tried everything I can think of to either remove the original adhesive (bit rubbery like Evo-stick contact type glue) or stick the batons to cleared off surface, by scraping the glue with a chisel-hard work and just sort of moves it around, cleaning with acetone- just goes gooey, orange oil based sticky stuff remover- smells nice but doesn't do anything, wire brush-hand or electric drill, flap disc on electric drill- sort of heats it up and smears it but not remove it.
"No Nails" adhesive on any bare fibreglass doesn't stay stuck to the fibreglass, "Super Glue"- breaks away.
This is a project that has been ongoing for years now and making me crazy. Please help me?
Many thanks for your time and helpful advice.DC

You need to find the right solvent for the glue, I am assuming it may be the yellow type contact adhesive? If so I recently discovered that an aerosol can of Carburetor cleaner works pretty well as you can spray a good dose of it on to get it softer, then it can mostly scrape off plus a bit more solvent and wiping etc. Then abrade where your battons will stick and use an elastic adhesive like sikaflex to bond the batton/batten.

Ok thank you for your information, I'll give it go.
