3M Scotchcast 82003V Plus Casting Tape, Bright Green 3" x 4 Yard (Pack of 10)

does it expires? how long is it good for when its sealed? ok so i use it to cast a leg on the farm. we rarely have broken legs

Could you use part of the roll and save the rest for later in a platic baggy if you don't get it wet?

Can this be cut length wise before wetting to make thinner strips?

Can this product be used for other things?
