I used to hang vinyl siding for Sears. Back then I could run a bead of caulk that didn't need touching up. It was perfect. I guess that's a skill you lose over time without practice. I just re-caulked my shower. What a mess! LOL. There was caulk everywhere. All over the bottom tiles, all over me. I had to go back and re-touch every line with my finger. Yuck. But, at least I know it is done right and will last until we move out of this apartment. I wish the boy weren't sick so I could have showed him how to do it. Ahh well, I still have to caulk the tub once this is dry. Perhaps then.
