No, but a g/friend of mine used "ZeroRust" inside her Bronco, a similar product. Took about two days to cure, but hard as a rock. I have a quart to put in my Bronco after the roll cage goes in.
I had never heard of the stuff before. I found their web site and I'm thinking of putting it down in my garage. I've emailed them for some info, I'm not decided yet though.
