These paints are simply superb. Firstly, the coverage of these metallic paints is so good that very little is required – a very small blob in a paint dish, and thinned with white spirit will go a long way. Even better, because the paints are super-fine metallic particles in a wax base, even if the paint is allowed to dry up in the dish, it can be re-activated with a paintbrush dipped in white spirit a couple of times. Realistically, for the average modeller, a tube will last a long time, making it great value. Secondly, thin down a bit more with white spirit and it can be used in an airbrush, achieving an amazing result. Once allowed to dry, this paint can be polished with a soft cloth to achieve a totally realistic metal finish. I really can't recommend these paints enough – they even smell nice!
