FiberFix Flex Tape/Patches are 1 time use per package
i just saw the info on not being able to reuse FiberFix in comments on the FiberFix website. Also, several users were surly about receiving material that was not usable (suspected the packaging had been damaged), so be sure to check the flexibility of your tape/patches when you buy it, protect the packaging from punctures, and use it all at once!
On the Tyvek tape, other reviewers agreed that the white tape with blue lettering was superior and that it can become permanent if not removed for a permanent patch. Alpaca echoes this warning in their repair instructions for their packrafts.
Stay wet my friends!
