1/3 of the 12oz can is way more enough for 2 reflectors.
you will also need 12 oz. Touch Up High Gloss Clear Coat and 12 oz Aerosol Plastic Parts Adhesion Promoter.

also you need a new roll of 3M molding tape to replace the old one, once they are off they don't stick anymore.

very important, take time to apply paint, spray thin coat one feet away per each coat till it covers all. let them dry before other coat (i wait about 20 to 25 min per coat). and make sure no dust around. it is a great weekend project
