How To Spray Paint Your Gun 

Metal paint is the best type of paint for guns. Some paint types need to air-dry, while others require baking in a toaster oven to set the paint finish. Air-drying paint will give you a far better paint finish than paint that requires an oven.

Note that you can choose to paint your gun as a whole or disassemble your gun to paint individual metal parts separately by using masking tape. 

After you paint using masking tape, ensure you seek help from a gun expert or online manual to reassemble your gun. 

Can Regular Paint Be Used? 

Regular paint can be used on a gun, but it will not give you the same metal spray paint result. In addition, regular paint is not as durable, and there's little color variety. It is also more likely to chip over time.
