Mark Russell's review was from 2 years ago, so  things have probably changed, but the garage seal I received (sold and shipped by Amazon) is indeed the tough, rubbery EPDM version that does not tear easily (or at all). And as a result of the better rubber compound, 3M mounting tapes will not sure to it... I bought this to add a lip to my cars as many others have done but no 3M mounting tape (permanent outdoor, Extreme outdoor, etc) will work, even with properly cleaning the surface and heating the tape. I did find out that I'll have to prep the EPDM surface with 3M tape Primer 94, which should get the mounting tapes I have to bond permanently.
