Now its enough....
Those seaming kits come with glove, copious amounts of primer, but only one roll of tape. This is the same tape that comes in seaming kits and you can buy this separately. Awesome!
works well - don't forget the primer
Purchased this as I was extending my waterfall and needed to add some extra liner. This worked like a charm. Don't forget to order primer though! I ordered the firestone primer and it worked well.
