Hot take: Most people use way too much filler on small dents
I was at a buddy's shop last Tuesday watching him fix a quarter panel ding on a Civic. He globbed on a huge amount of filler, sanded for 20 minutes, and still had to redo it twice. I told him to try a thin layer instead, just enough to cover the low spot. He looked at me like I had three heads, but I showed him a spot repair I did on a 2018 Ford F-150 bumper last month. That job took me half the time and barely any sanding, and the customer couldn't tell it was ever hit. Filler is for leveling, not building. If you need more than 1/8 inch, you either missed some metal work or you're creating more work for yourself. Has anyone else found that going light on filler actually saves time in the long run?
