Quoted from Zee:Oh that's interesting! Sort of a small quantity catalyzed clear.
It is a two-part clear in a can. There are two chambers and you puncture it on the bottom and they mix and are usable for 48 hours. Just about 1 can per coat for a playfield so it works well. I have a compressor and gun but without a properly vented paint-booth it feels kind of unsafe for me and my neighbors. This stuff is way more modest in output and feels a lot safer. It is also more convenient because of the small paint booth.
It is not cheap at about $20 per can and you can't make many adjustments (spray pattern, pressure, mix, etc) but it seems to be a pretty good finish overall. There is a whole thread about it over here:
