picked up a blast cabinet

[JointTech]

my buddy saw this on the side of the road. Got it for $60. Gloves are shot. Looks like theres some kind of long spring that holds the door on the bottom of the media holder but it came off and the spring looks sprung. light works.
I was going to clean it up and paint it but I think Ill just clean it up and fix the gloves and call it good until I get a paint setup. Im sick of rattle cans.

It has a matco sticker on it but Im not sure it really is.

now to find something that needs blasting.

What media should I get? Anything to watch out for? Looks like you just hook up the air and it create a suction and blows it out the gun?
What pressure does it need to run at?
