I just was browsing through a local art stores website when I came across this spray paint.

It says that it dries matte, so I'm thinking that it should work as a primer for models, but I thought I'd ask to see if any of you guys out there have had experience using this.
It's a bit more expensive than what I'm used to paying for primer. Usually I just get Krylon Flat Black for a few bucks at Walmart, but I'm on my painting table is about 30 Daemonettes that need to get painted as well as 20 Seekers and it's a pain in the butt to go from a black base to the light purple I'm aiming for. So when I saw that Plutonium offers a huge variety of colors (one of them being the light purple I've been looking for) it would really make painting a lot of Daemonettes pretty easy! My daemon army could go from an semi-agonizing experience to one of ease!
So yeah if you've had experience using this spray paint, let me know what you think about it!
