Sturdy useful tool make job go faster

Would Recommend

Whole lot better than using your finger. Even, smooth, fast filling and inside corner prep for paint. Rubber triangle fills in nail / screw holes very well. Just an all-around useful tool. If you need pictures, you haven't done much calking. I keep a plastic coffee can with 2~3 inches of water around, just swish it around a bit in the water, keeps from build-up and clumping / causing streaks. Make the job go faster, Well worth the money.

Handy tool

Would Recommend

The tool works great for removing old caulking and applying new caulking. I used my fingers before and that was always messy this tool gives you three options for how wide you want your bead.
