Step 4: Paint!
Classic spraypaint technique here: spray in sweeping motions with a little bit of overlap. Apply thin coats and let each one dry for a little bit before going over it again. Keep moving and be sure to hit the surface from multiple angles.
The paint dries to the touch in 15 minutes, but can only be handled after 1 hour. For it to be fully chip resistant, you'll need to wait a week.
