Has anyone ever put anything like Rhino lining in their bilge area? Someone mentioned it to me today but thought I wasnt sure if that would work well.

Discussed before and the concensus was that it was not a good idea.

What would be some of the concerns?

ever getting it off if you needed to....transom, stringer work, changing color, etc....

I would think it would be hard to clean up. It's not smooth at all. I put on awlgrip and oil leaks come up like it was water, nice and easy. It may also hide any future structural problems you may have.

heavy as hell and if water layed there and if started getting under it.....think it would be one hell of a mess

10 years here. Works GREAT with gas and oil. It did lift back by the leaking cap on trim pump(1/2 sq ft)??!! Painted this area (with paint) 6 years ago matching with a brush and it has stayed intact very well. I would do it again.
