Questions about this tube
How cold can I apply Extreme?
It is formulated to gun and bond in extreme cold; keep the cartridge in the cab so it flows, and brush frost off the lumber.
Is Extreme stronger than regular Heavy Duty?
Yes. It delivers more than double the holding strength of fasteners alone and keeps bonding where standard formulas stall in heat and cold.
