One sample is worth several conjectures.   I have used the same grey carpet
now for several years.  Other than being more soiled than it was, it has
held up fine to animal barf, coffee, loud music, pasta, blood, tea,
coca-cola, bug guts and various other abuses.  AND should you have to
replace it in the future, it is easily removable to use as a pattern for the
next expendable set.  The stuff is rated as outdoor carpet so since mine is
'indoors' I might expect it's UV lifetime to be longer than the remaining
lifetime of a 15 yr old  190Kmi Syncro Westie.  YMMV mine always does.

cheers,

Al
