84 degrees in my buddy's garage and we spent 3 hours on a single lower strut bolt one time. PB Blaster the night before helps but heat and a good six point socket are what really save you. Impact wrench on high just makes the round worse.

I was the same way about those mats for years, swore they were a scam after one bad batch. Then my sister in Topeka gave me hers and now I use it for every single tray of cookies. Honestly it fixed the burning way more than any pan swap ever did.

That "within 3C" number tracks with what a buddy of mine saw at his shop, he had a stack of old Latitudes and swore the paste was shot on all of them. He tested half with stock paste and half repasted, and the temp gap was small enough that he stopped doing it by default too. Turns out most of those units just needed the dust blown out of the heatsink, not a full teardown.
