Unpopular opinion: I tried using a cheap bondo dispenser gun and it clogged on the second panel
I picked up a $25 bondo dispenser from an auto parts store in Tucson thinking it would speed up my filler work. It worked great for the first dolly shot, but then the plunger jammed and I had to scrape out half-set filler from the nozzle. Learned my lesson: stick with mixing by hand on a clean board, it's slower but way less frustrating. Anyone else had bad luck with these guns or is it just me?

Yeah I had one of those cheap bondo guns from Harbor Freight in 2019. The metal plunger rod bent on the third squeeze and the whole thing seized up. I tried to take it apart but the threads stripped. Ended up tossing it in the scrap bin and went back to using a 6 inch drywall knife on a piece of cardboard. The manual mixing gives me time to work the filler in better too. Plus no waste from dried junk in the nozzle.

Three squeezes and it bent? Sounds like you got a dud or maybe you were trying to mix a concrete batch with it. I've had the same cheap Harbor Freight caulk gun for two years and it still works fine for the occasional tube of silicone. That said, I don't use it for bondo either - different tool for a different job.
