Lay out the newspaper so that it covers an area two feet larger than the area of the club shaft your are going to paint.
Rub down the club shaft with the sandpaper using a gentle, even stroke. This will remove most of the galvanized finish and provide a better surface for the paint to adhere to. Wipe down the club shaft with a cloth to remove any dust.
Cover the grip and the head of the club with the plastic wrap and secure the plastic with the painter's tape. Make sure that the plastic is covering any part of the club you do not want to be painted.
Paint the shaft in an acrylic or latex-based galvanized metal primer. Be careful not to over-paint the shaft. You only need a thin layer. Allow the primer to adequately dry.
Spray the metallic spray paint on the club shaft. Use a steady, even motion to apply the coat of paint evenly and rotate the shaft with the hand that is not applying the paint.
Lay the golf club on the two wooden blocks, placing one block under the grip and one under the club head, lying the club over the newspaper.
