As promised, a report on the garage floor mats that were brought up on another thread which is probably forgotten now...
I still like them. They're not perfect, nothing is, the paints lifts over time, the vinyl tiles were dangerous (long story) and impossible to remove, the race-deck stuff is horrendously expensive, so I tried these to cover my nasty vinyl tiles !
As you can see it's not perfect, the rubber mat seems to have little bumps or stretches here and there, but it's a hell of a lot nicer than it was before, and I can take them with me...
For <$600, I like my garage floor better, now!
