Congratulations!
While it's still clean and empty, I'd recommend a bead of good RTV silicone on every seam unless you like a dusty shop.
You'll also want to bookmark a place called
TPTools.com right now. They have great quality consumables (gloves, carbide tips that will outlast the cheap pink ceramic one yours probably came with, plastic sheets to protect the window, etc.), good prices and decent customer service. I expect you'll soon want one of their blast gun upgrade kits too.
Yayyyy new tools!! Yesterday while getting the shop heater ready for the season, I found my favorite pliers up on top of the upper wall beam, missing for at least two years now. It made my day!
