My New Garage

Awesome Shop!!!
I have one recommendation. If that heater you have mounted in the corner is vent less replace it ASAP with a vented unit heater or Rinnai vented wall heater. Those heaters are basically Humidifiers and will be introducing gallons of water to your tools and car on a daily basis. If its Electric disregard my post, except the part that your shop looks awesome!
I also have 2 ceiling fans on circulating air 24/7. I'm not sure if that helps but I honestly don't see any indication of moisture. I honestly hope everything is ok.
