Just realized I'm the odd one out on using bondo for everything
Last Tuesday at the shop on Elm Street, I watched a guy spend 3 hours hammering out a dent on a 2018 Civic when I could have had it filled and sanded in 45 minutes. I know everyone in this trade loves the 'proper' way of metalwork, but I've been using filler on daily drivers for 6 years and never had a comeback. My old boss taught me that if you prep right and keep the coat under 1/8 inch, it holds up fine. Can someone explain why the hate for bondo is so strong?

My buddy Jake used bondo to patch a quarter panel on his 94 F-150 back in 2017. Two years later we pulled the carpet and found the floorboards had rusted clean through from trapped moisture behind that patch. He lost the whole cab floor, had to weld in new metal from a junkyard truck. That stuff seals in water if the backside isn't sealed too, and nobody ever seals the backside on a daily driver.
