This may be a little of topic... but has anybody thought about the roll-on truck bedliner as a garage floor?
It may be hard to clean because or the roughness of it, but it will provide superior wet traction.
The only reason I am asking this is because one of my friends swears by the home depot (don't know the actual manufacturer name) brand of truck bedliner. He has used it on numerous boats, off-road vehicles, trailers, etc. and in the 3 years I have known him it has not let him down.
I don't know about the moisture protection, but I am just wondering if this was ever thought of as an alternative solution?
