At the risk of beating this issue to death, I just wanted to mention that the building manual often instructs to sand then clean with MC, vs. clean then sand. Also, sometimes 40 grit is recommended instead of 80. If anyone out there wishes to comment on the reasons for the different procedures, please do so. I reckon for the truly "anal retentive", cleaning first with pure MC (to keep from "sanding in" impurities), then sanding/roughing, followed by another pure MC cleaning, would be the optimal procedure ...??? Whatever it takes to get a thoroughly clean part. Also, yes MC will evaporate in a hot garage/workshop. A buddy of mine that owns a fiberglass repair shop gave me a couple of pints of MC in a bottle about mid week. When I checked on it on the weekend, it was history, completely gone! Maybe the cap was a little loose - don't know. The peak temps in my garage during the hot summers here in Southern Louisiana typically run in the 80 - 95 degree range.
