I am guilty of doing some laughable body work over the years. Everywhere from using latex house paint to paint rocker panels, to filling a 6 inch wide dent entirely with bondo, but I have since matured and moved on to being able to do somewhat passable work. What I was wondering is what is the worst attempt at rust/dent repair you have seen? I am yet to see someone use drywall filler on rocker panels, but I've seen plenty of expand-a-foam and duct tape. My thing is rivets and galvanized sheet metal, though I do weld some patches in. (I used Rivets, duct sheet metal, and furnace tape to fix the smashed bumper on my moms '07 suburban) What is the worst you've seen/done?
