Prepare for Exterior Caulking

What happens here

Move to the exterior of the window. Observe the size of the gaps around the window frame. If they are larger than the interior gaps, cut a slightly wider opening on the caulk tube tip, still maintaining the 45-degree angle, to allow for more caulk output. For significantly large gaps (e.g., half an inch or more), consider inserting a backer rod into the gap before applying caulk. This technique helps fill large voids, reduces the amount of caulk needed, and ensures proper caulk flexibility, although it wasn't explicitly needed for the exterior window shown in the video.

Goal: Assess exterior window gaps, and if larger, cut a wider opening on the caulk tube tip to accommodate them. Consider using backer rod for very large gaps.
