Can The Air Spray Gun use all Paints?

No, it depends on the viscosity of the paint and the object what you painted. 

And WHY?
If the paint is a high viscosity and has not been diluted with thinner, it cannot be sprayed directly with a spray gun because the liquid flows slowly inside and can clog the air passage and nozzle over time. It is common to use thinned paints for spraying, either oil-based paints thinned with spirits minerals or water-based paints thinned with solvent or water, ensuring the flow of paint. The airless spray guns are available for undiluted paint. The principle of the airless spray gun is to atomize the liquid paint directly with high pressure, which places high demands on the air compressor and nozzle.
