Old Chuck knew what he was talking about. Speed kills on a big slab, especially in Phoenix heat where that concrete sets up quick. I had a similar thing happen on a warehouse floor where my buddy slowed me down by pointing out my edges were curling. That extra 30 seconds per pull on the trowel saved us a whole day of grinding later. You learn that smooth and steady beats fast and sloppy every time.

Funny you mention that, a buddy of mine had the exact same thing happen with his dad's old trick for sticking formica to particle board. His dad told him to rough up the surface with a fine grit sandpaper and then wipe it down with mineral spirits before glue up. My buddy laughed and did it his own way for years, kept getting delamination on edges. Finally gave in one day out of desperation, sanded and wiped with spirits, and that stuff stuck like crazy. He texted me a picture of the joint a year later and it still looked perfect. Makes you wonder how many old school methods got lost just because they sounded too simple or dumb to try.

Can't believe they tried to sneak "and related materials" past you. That one phrase could mean anything from coffee receipts to internal Slack messages. I had a client once ask for "all drafts" and we ended up having to catalog every single version of a design file, including the ones we deleted from the trash. It's wild how three words can turn a two hour job into a two week headache.

Yeah, that tracks. Old timers swear by that stuff like it's snake oil but somehow it works. I had a guy tell me to pour ATF down a stuck carburetor on a pickup once, thought he was pulling my leg. Tried it anyway, thing coughed and fired right up after sitting for two years. Now I keep a can of Seafoam handy just in case, but diesel in the fuel tank sounds like some hardcore 70s logic that probably does the trick. Just don't tell the EPA guys about it or they'll have a heart attack.

@black.oliver did you at least try to get a refund before calling it a loss?
