Galling on 316" sounds about right. I swear that stuff has a personal grudge against thread mills. But yeah, I had a guy catch our coolant at 2% once and the whole shop was acting like it was a mystery why taps kept snapping. One bottle of concentrate later and suddenly everyone's a hero. Glad it wasn't just me burning through $90 inserts for a free lesson in fluid maintenance.

Did you ever just trust clicks over cash before that week changed your mind?

Man that old timer knew his stuff. I burned up a whole alternator harness on my 91 Ranger last year because I was too lazy to spend 12 bucks on split loom. The wire chafed against a bracket for months and I ignored the flickering dash lights till it finally grounded out and killed my battery on the interstate. Cost me 90 bucks for a tow plus 60 for a used harness, so I feel your pain on that tape and zip tie trap.
