You might want to check out Hull
Liner. It's readily available. Here's a link. I am by no means endorsing this company. It's just the first one I found on the Internet
with general information.
We replaced portions of the head
liner and wall covering in Sunspot Baby with light blue Hull
Liner. It is supposedly mildew and stain resistant. Having acquired a stain or two already (rust from a light fixture) that "almost" came out, I wonder if we should have picked a slightly darker color.
Installed directly to fiberglass
, the light filters through and shows flaws in the fiberglass
. Backings are available, but then we have the issue of the backing disintegrating, the liner not staying put, etc.
If anyone has other experiences to share about Hull Liner, I would be interested, because we might continue to install it on other areas of the boat. When we were searching for a boat, I liked the upholstered look. At this point, the white fiberglass interior
walls and ceilings look great to me now.
