Questions about this tube
Is a 28 oz Extreme worth it over three 10 oz tubes?
On a deck or a wall of siding, yes: fewer cartridge changes and a continuous bead per board.
Can it be applied in the rain?
Surfaces should be free of standing water, but damp lumber and cold are fine; the formula is built for weather.
