Great Product!
By NWB from Maine

This tape is much better quality than I've bought from other suppliers. The others wouldn't stick at all (not allowing to draw a vacuum) but this product worked as described/expected. It worked great on a small carbon fiber layup I recently did. And as always the super-fast shipping from Jamestown is GREAT!

Bottom Line Yes, I would recommend to a friend
