best vacuum infusion bag sealant that i know.


apply this double sided tape and it never hardens up or dries out. It is thick and yet pliable. it doesn't stick to your fingers.

Great Product!


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!




Sealing Tape Wonder!


I tried another companies sealing tape, and lets just say it cost me, however Jamestown was here to save me with extremely fast shipping, and this sealing tape was 3 times better than the "others" out there!Love the products Jamestown
