I went down to Margate yesterday and had a great time at the Hornby factory! Thanks guys, a great experience and a really great sausage roll! And in the shop I discovered the acrylic dropper bottles. Now I am no expert so asked the assistant if they needed to be thinned for airbrush? He said they did not, they are airbrush ready. In fact there is an airbrush symbol on the bottle with a tick next to it which suggests this is correct. However, having bought a couple of bottles, and having shaken them as instructed, the paint comes out like toothpaste. That's not going to find it's way out of my airbrush! So was the assistant correct and the paint is faulty? Or did the assistant make a mistake and it's not airbrush ready? Thanks
