Great!
Glad to hear most of my fears were unfounded. I'll have to find some air tool oil somewhere and put a bit in the hose coming off the compressor. DonRotolo was right about moisture here in LA, especially in New Orleans.
I was thinking of putting some of those pellets that are found in those little packets that remove moisture from the air in the two main tanks as well, considering just how high humidity is year round here. Any thoughts?
Edit: BAD IDEA.
About ten seconds of thought after this post and it occurred to me that doing so would just be asking for one of those to get sucked up and lodged in a solenoid!
Thanks to everyone who replied!
