Well, Nicolas, I have seen some - but not many that have put up a marine head liner. The vast majority of other Bolers I have seen (run
fiberglass meets here in BC which
Boler is the most popular trailer) normally use a caulking to fill all the seams and holes in the wall covering and then they use a oil based
paint or a kitchen and bath type
paint with a semi gloss finish that stands up to wear and can be washed.
