Remember when we had to mix all the body filler by hand?
I was cleaning out the back of my shop in Toledo and found my old mixing board from maybe 15 years ago, all crusted over. Back then, you had to guess the ratios and stir it fast before it set up. Now my new guy just grabs the pre-measured tubes and uses the mixing gun, gets a perfect mix every single time in about ten seconds. It's wild how much time that saves on a big job. What's the one old-school task you're glad got easier?
