For a play car (open track or pro-touring) I'd say the only reason NOT to use it would be weight.
It does not deaden sound as well as a quality underlayment. It does not seal against rust as well as POR-15. It is not as attractive and comfortable as carpet.
But it does all three of those better than any other ONE of those appraches.
Well, for my drag car, weight is an issue, but I doubt 5# or so will be that much of a deal, I don't have a weight to make, just want it as light as possible.
Most drag cars, even with carpet, normally have no sound deadening and if they do, it's that grey insulation backing, but they sound real 'tinny' anyway, something about the open exhaust in close proximity to the ground likely does it. This stuff would reduce that to an extent.
Being a drag only car and spending time in the garage when not racing, rust shouldn't be an issue. My car will be media blasted before paint and all rust replaced, the coating will be on the inside, not the outside, so I think I'd be okay.
Attractive, maybe not, comfort is of no issue really, carpet or no in a loud drag car on days of 100+ with no A/C and no windows to roll down, I don't think I'll notice that the floor isn't cushy under my feet.
I understand it wouldn't be for everyone, but in my application, I think it would work well. My car is a sort of T-bolt clone and the original T-bolts had a vinyl floor in them anyway. I'm not so concerned with fire as I plan on having a suppression system installed along with an engine diaper. It's an extra $1500 or so, but if it keeps it off the wall, off it's top, or from burning to the ground (hard to get insurance on a drag only car) I figure it's worth it.
