Marty Hotes of Vandermeer Forest Products demonstrates G-Tape’s 3040BK flashing and 1009GR surface-protection tapes. G-Tape easily tears off from the roll and does not stick to itself, and reworking it is a breeze. The company's 3040BK flashing tape is workable up to 30 minutes and fully adheres in hours; multiple roll-width sizes are available.
