>>11279236you don't need a spray booth or to go outside so it's probably nice if you live somewhere where the weather is too shitty to paint, or in a soulless concrete apartment with no yard/balcony (and dont wanna invest in an airbrush+spraybooth)
looks like the process of dabbing it on with a sponge would be very slow and tedious for a big / high partcount model kit compared to spraying though, this guy is only doing it for faces
