All model air brushes are operated from a compressed gas supply - either a compressor or a compressed gas can of propellant. Most paints will require thinning - consistency is important for best results.

Parts to be painted should be completely free of dust and grease. Use filler and sandpaper to smooth uneven surfaces. Although not essential, giving a first coat of primer can help ensure paint adheres better and gives a better coverage. Uniform application with full coverage is the golden rule for painting. Don't overdo it or runs will occur. Build up the density gradually. Allow the painted parts to dry in a dust free room. Once completely dry, repeat the process to get a perfect finish.

 For best results experiment with paint consistency - most will require thinning - and nozzle size as recommended by the manufacturer.
