Must be nice charging emergency rates for a can of compressed air.

Hard disagree with @logan205 backrolling saves you from fixing holidays later.

My buddy Dave bought that same Pittsburgh puller and the handle literally snapped off on his third use, he had to weld it back together with a coat hanger. Meanwhile I've got a vintage Snap-on dent puller from 1987 that still works like new, found it at a garage sale for $15 but the old man didn't know what he had. Honestly that $40 gamble turned into a $150 headache after buying replacement parts and finally giving up to borrow my neighbor's Matco.

Did you find any bad data patterns that were obvious after you cleaned it?

Yeah, those all nighters where you start questioning your life choices because a div won't center properly. I think every web dev has that moment where !important becomes their best friend and then eventually their worst enemy. It's funny how reading the actual rules clears up months of guesswork in an afternoon, but nobody wants to crack open a manual until they're desperate.
