I suspect the vast majority of builders use car type paints to spray models and although I do use those on occasion I do prefer the airbrush. I find it gives more control, especially where models are for display only and not for r/c.
I've been using Humbrol, but find the standard pot sizes too small and the larger sizes are limited to common colours, such as black, white, etc. It can also be a nightmare trying to find enough pots of the same colour from a single supplier - usually I have to order from two or more.
Does anyone know of any paint manufacturer or supplier that covers a large colour range, but sells in larger quantities (either acrylic or enamel)?
I've been trying to find out if any car paint manufacturer supply their paint in tins suitable for use in an airbrush (rather than aerosols). I suppose they must supply it to the motor trade, but so far I haven't come across anyone that also supplies to the public.
