Types of Paint

Modelling paints are generally of two types: (oil-based) enamels, or aqueous (water-based) acrylic lacquers. The hobby enamels thin with mineral spirits, dry slowly and stiffen to a glossy finish. The hobby acrylics thin with water or alcohol, dry quicker, and clean up easier. Never mix enamel with acrylic, and double check that you use the correct type of thinner.

Brush

The paintbrush is the easiest technique of coating your model in paint. You'll need a big flat brush for large area coverage, a medium diameter round brush for general use, and a fine-point brush for the smallest detaillingl. The keys to getting a smooth paint job are:

-Use a new brush.
-Don't overlap brush strokes. Don't paint ontop of an area with moist paint. If needed, let the paint dry, then apply a second coat.
-Use a brush with soft bristles, sable is best.
-For a wide area, use a wide brush to minimize the number of strokes.
-Keep dried paint flakes out of your paint bottle. Use a straw or throw away dropper when transferring paint.
-For acrylic paints, try adding a little amount of paint thinner, or acrylic paint retarder.
-Practice on scrap plastic before painting your model plane.
-After using the brush, clean up straight away with the recommended thinner.

Spray Can

The spray paint can is also widely used for model painting. The spray tin:
-Gives a smoother paint job with no brush marks.
-Is quicker than brushing.
-Requires less cleaning.
-However, cans of paint deliver a wider area spray and so are somewhat wasteful and more expensive. Also, there is a minimal choice of colors available, and it is not possible to create your own colors little scale models. When used in conjuction with a compressor as the air source, it behaves as a very big spray tin, while also allowing control of the pressure and the amount of paint. The airbrush can also be used to create fine strips of paint and many other useful effects. Some basic tips:

-A single action airbrush is easier to learn, and generally lower priced. However, the double action gives you more control over the paint job.
-A compressor is less expensive in the long run than using tins of compressed air.
-Use the paint maker's recommended thinner. This will sustain the paints flowing smoothly without drying too quickly.
-Follow the instructions for cleaning up, to keep the airbrush working properly.
