What is tinners tape?

Tinners tape is used on heating ducts. You could use aluminum foil too, it just will come off easier because it isn't sticky.
ok thanks. tried your nerf to airsoft thing. Works great.

It is very nice and you can use it for other purposes also like have one end of the thread in a band and wear it in your hand and the other end with the clip inside your wallet or purse so when someone snatches it the alarm will go off
