Apply Caulk to Interior Window Frame

What happens here

Hold the caulk gun with the 45-degree angled tip flat against the interior window surface. Apply a steady bead of caulk, watching to ensure the gap is being filled. Move slowly and deliberately. The goal is to apply just enough caulk to fill the gap, as applying too much will lead to wasted material and a mess that needs extensive wiping.

Goal: Apply a bead of caulk along the interior window frame, ensuring the caulk gun tip is at a 45-degree angle and pushing the caulk into the crack without over-applying.
