Blank canvas, steel sided 40x60 pole barn. Thoughts on insulating, electrical, heating???

Absolutely no offense taken! I'm an old Jarhead. We don't get butt hurt. I didn't realize you had more than one garage. Mine is also heated and cooled with 2 heat pumps. Rob(Rumblefish) has been here and lost his mind. I'm currently making the old dyno room into a paint booth. The PO left all the exhaust fans for me. I'm working on the compressed air filter/dryer now. I'm not trying to one up you, but I can't afford %15,000 for a paint job. I have the room, so I'll learn to paint it myself. Upon a closer look, I see a pretty young lady in the Dart, too. Any FABO family members are welcome to visit if they're in the area.
