Appreciation post: Hit 500 service calls without a single callback for a bad install

Just hit the number this week, and it honestly shocked me. It's not about luck, it's about taking the extra ten minutes to check every wire and sensor before you leave the job. I had a run of three jobs in a row last year where I almost rushed and would have missed a loose door contact. Anyone else track a stat like this, or am I just weird?

Hot take: I used to run my coolant at a 5% mix for everything, but now I run it at 8% for aluminum and 3% for steel.

I had a string of bad finishes on some 6061 parts last year, and an old timer at the tooling supplier in Akron told me to bump up the concentration. The extra lube made a huge difference on the soft stuff, but it was just wasting money on harder materials. What's your go-to coolant mix for different jobs?
