[BR3W CITY]

I've done a little work in a hot garage in about 80%+ humidity, and its tough for a couple reasons.
It gets hot and steamy, and you risk condensation forming on stuff and/or ending up on your paint, and if you don't have a really big compressor that doesn't have to run often...you'll find that your comp pushes lots of water, and you'll be emptying both the on-tank and inline water separators often
