You got it in one. Little pressure, high grits and patience produce a VERY nice end product, lower grits and muscle can do much the same but the finish isn't the same. We're going for engineer-quality flatness, not pretty. I'll take the time to do it right rather than have temps be worse than they were before.

As to temps, I'm still sorting things with the cooler I'm reviewing. The cooler may well be bad, as well. We've seen some inconsistencies thus far, and I'd like to investigate them further.
