This stuff is good! I've only used it on 4 test models so far, but it just feels right. It is more of a puff than a spray but it coats evenly and quickly. I'm just using grey but it comes in a wide range of colors. The down side is it costs about the same as GW brand stuff. Though I will probably stick with this stuff since it seems to work well for me and comes in colors. I'm going to go back outside and keep using it, I'll comment if anything comes up that changes my opinion.
Also sorry for the sporadic posts, I'll see if I can't get more posted consistently.
