I received my order of edge paints this week, I got the full set and from what I can tell they are almost the exact same colours as the dry paints but with the same consistency as the layer paints range.
I am not usually a fan of edge highlights but I will use it some times to help make something pop. I had a root through my collection for a model that I could try these paints out on and decided that my recently painted Vindicare Assassin was the perfect candidate as he is an army of one.
So I went back in and added some extreme edge highlights to as much of him as I could and tbh it does make him look more Sci-Fi and helps him stand out that extra bit above the rest of my Imperial Guard army.
This is the Vindicare before I went in with the edges paints.
And here he is afterwards.
So while not ground breaking I can see these paints being quite nice for the extreme highlight on something that really needs to stand out and I expect I will use them more as time goes on.
Check back soon :)
