I saw some other pictures of it being assembled and the lights were wrapped until the fabric was on. It’s also relatively rare for moving heads to be IP rated because they move, and in order to maintain IP rating on something that moves it requires significantly more maintenance and with that, higher cost. The lights that are on the outside are IP rated for instance, as they didn’t have the fabric to protect them. But from prior experience that means those lights cost about 3 times as much to rent.

The chains are protected by a coating of oil, the oil is in a reservoir inside the motor so if the chains aren’t getting ran on a regular basis they aren’t getting a fresh coat of oil. As soon as any sort of weathering happens, the chains become exposed and will start rusting. You can get stainless steel chains that won’t rust, but the price on those is so astronomical, that it’s special order only, and only used for permanent installs. The only way this has stainless steel chains is if it was designed as a permanent install from the beginning.
