Just a quick update, Mother Nature is fighting me on these damn shells, another sub zero week in the Midwest has pretty much stopped all progress… I tried the other day to get the garage up to temp so I could at least do a test pull to show everyone, but after 6 hours full throttle on the 60,000 BTU heater the best I was able to do is to get the garage up to 55 degrees, not the 70 degrees I need to do fiberglass… This week looks like it’s going to be in the 20s so I will try again in the next few days… Sorry about the delays, I knew winter was going to cause some issues, but I never expected extended subzero weather… --- _[View the full topic](https://forum.gbfans.com/t/the-v71-mark-x-fiberglass-shell/33794)._
