Caulk Application Test: M12 Speed Control

What happens here

The presenter cuts the tip of a DAP Dynaflex 230 caulk tube with a Milwaukee Fastback utility knife. He then loads the M12 caulk gun and tests it on a wooden board. He experiments with different speed settings, noting that speed 1 produces almost no caulk, while speed 9 results in a large, messy bead. He then tries speed 3.5, which is still too much, and finally settles on speed 2 as a more realistic and controllable setting for typical applications. He concludes that the higher speeds are best suited for large-volume applications like subflooring.

Goal: Evaluate the M12 caulk gun's performance at various speed settings.
