I put a variant of Hurculiner on my floor boards, called Vitaliner, bought from JC Whitney. I only put 2 coats on as opposed to 3, called for, and I have a very hard time beleiving that it's heavier than carpeting. Plus, it's only applied in on the floor board itself and the rest is trunk paint. I'm very pleased with it. The Vitaliner is water soluble, easier to apply, and has better traction than the Herculiner.
