OK, this isn't the best matte coat I ever seen, but it is very convenient to airbrush with. Literally pour some into the brush and spray away. The problem (it's not too much of a issue) is that it has a slight hint of yellow. It's very VERY subtle but can be noticed if you're looking for it. It's also not very matte when compared to Mr Hobby dull spray or Tamiya flat coats.

So why the five star? Well it's very convenient to use. It's perfect for those small parts that you want to make more matte, but not so much the larger surface areas since the hint of yellow might be spotted. It's also cheap compared to other flat coats.
