My Boler was found sitting in a field in Alberta. It was there without any windows for about 4 years. the lining is torn in many places and there is alot of moisture in behind the lining below the front and rear windows. worrying about mold and such, i figure the best thing to do would be to get rid of that old lining. also, kids have painted it pink!
Sight unseen, I don't know what exactly you are dealing with. Can you post some pictures? A lot of people have been able to overcome problems with mold and ensolite. You can do a search here for both. There are many techniques people have used. Having only reglued sections of the ensolite I can't imagine cutting and glueing new from scratch.
Here is a link
to our Boler that had a hole in the roof and was left in a wooded area for about 10 years. It had mold, the ensolite was fallling down and the seam tape was in rough shape. Although we have not quite finished it yet, the ensolite is almost ready for painting
. We plan on getting that finished in the next couple of weeks. I hope to be able to post more pictures after then.
