wall coverings for fish rooms

[toxic111]

FRP panels is what I was thinking about. The cost isn't actually that bad. Home depot sometimes have it it stock. Barker board could be used as well. Used for tub surrounds & showers. Neither will fit in a car. That being the case go and check the paint stores. Not the home improvement stores. They may have something that will cover like paint and be water proof. You could also use a truck bed liner product. But that would probably be more than FRP panels. Hope all of this helps.
