BB guns are ideal to use for target practice, since they are less expensive than investing in an actual gun but provide the same type of practice for shooting. If you want to paint the BB gun, choose a dark colour with a smooth finish such as black or brown. Luckily, it doesn't require much precision because you don't have to worry about certain mechanisms.
Secure together two to three trash bags with masking tape to create a painting area so nothing will get paint splatters on it. You should set it up in a ventilated area. Put on the face mask, eye wear and gloves.
Dip the rag in acetone and wipe down the BB gun thoroughly. This will get rid of oils and debris so that the gun's surface holds the spray paint.
Use the masking tape to block off the parts of the BB gun you don't want to get paint on, such as the grip or the scope (if there is a scope). Simply tear off pieces of the masking tape and cover these areas.
Set the gun down flat on one side on top of the trash bags. Point the spray-paint can six inches away from the BB gun and spray directly across the gun in even sweeps, covering all the angles. Let dry for 30 minutes. Turn the gun over and repeat the process then let that side dry for 30 minutes.
Spray the paint into a disposable bowl and dip the sponge brush into the paint to cover the top and bottom of the BB gun, as well as all the nooks and angles. Apply the paint as smoothly as possible. Let dry.
Remove the masking tape and paint ragged edges if needed. Discard the masking tape.
Shake the spray paint cans well before each use
