I've been smoothing silicone with my fingers for as long as I can remember. But recently I watched a YouTube video showing the best way to use such tools. I have Zoro experience in this process and I have good results when I use it for the first time. It took a few tries and my learning curve was pretty good and I like the results especially I like the rim of the sink as shown in the picture. I didn't use all of the tools in this set, but it's good to have more options.
