Since this is just a cheap springer, I'm only going to tape the gun. If you are using a higher quality gun, you may want to remove any parts that cannot be painted. So, all you're going to want to do is cover or remove all parts that you don't want painted INCLUDING THE ORANGE TIP!!!!! Next, you are going to set up the paper/newspaper for your painting surface.
Step 3: Painting Side 1
Make sure tape is secure and you are ready to paint. Hold te can 10" away from the gun. Spray lightly and leave to dry.
Step 4: Painting Side 2
After side 1 is dry, flip the gun and repeat the process.
Step 5: Touch-Up
Hang the gun on a piece of twine. Add another light coat of paint. Leave to dry.
Step 6: Finished!!!
If you did it correctly, you should have a nicely painted gun! Go have fun!
