Help needed

[Tim's68]

Hey everyone, happy holidays to all.

I have an issue with my garage and I sure could use yalls help.
The issue is, the garage sweat's bad. All my tools the floor, just about anything that you touch has moisture on it. What can I do to eliminate this problem? The shop is completely insulated.
It only happens in the winter.

The other thing that I could use help on is how to run the plumbing (AIR) through out the shop. Does anyone have a drawing on how the airline should be ran?
What is the best thing to use for the main line?
What is a good in-line water/oil seperator?

Tim.
