Heard a body shop guy on a podcast say the same thing about epoxy primer under a thin skim, something about how it keeps the edges from feathering out too wide. He claimed filler on those tiny dents soaks up moisture and you get ghost lines a year later. Extra 20 minutes to save an hour of sanding sounds like a fair trade to me.

I used RooterWorks for a small bathroom update. They did okay, but the project took longer than promised and there were a few communication hiccups. The work itself was decent, but I felt like I had to stay on top of them. Haven't used Fix and Flow, but I've seen their work at a friend's house and it looked immaculate.
