I am currently using Tamiya acrylic paint on my kigurumi masks. It works OK, but it isn't particularly durable. I'm looking to switch to something better. I know there are a few kigurumi makers who use automotive 2K polyurethane paints, but those are only safe to spray in a fully enclosed spray booth with a supplied air respirator. I am aware of a couple places that are local to me that rent out spray booths and I'm planning to contact them, but if that doesn't work out, what do people here recommend for paints that are both reasonably durable and safe to spray without a fully enclosed spray booth and only a filter mask?
