Had mine for over 4 years now, was working on my x and laid my flashlight on the front passenger seat, didn't realize that the flashlight had corroded batteries and was leaking battery acid. the acid ate through the cloth but not through the neoprene, saved my factory cloth seats, I now have a whole for over a year in my seat cover about 3 inches in diameter but it hasn't spread or become worse, even with constant passnegers. Enough said.
