I have the Velcro strips to attach a seat upholstery buy in my boat. I thought to myself, if the strips are so strong, then keep wearing it from a cushion. Before cleaning, the Velcro strip on it and complained. One week wait before I again sat the first in the kayak and the strip have been tested. When dry, the pad on it, for correcting the pad again and there was even from the Velcro strips. Now I have to help with expander and the Velcro strips throw away because they are no longer sticky.
