1971 Truck Paint Job Blocking
|
I first began blocking with wet/dry 220-grit 3M paper. Begin using a hard block with a touch of water running over the block at all times. When blocking, use long strokes, 10-12 inches, to ensure the area is being sanded evenly. Short strokes will create sinkholes and low spots in the finish, a big no-no. Here's where the guide comes into play. Notice after a few strokes the unevenness of the finish is clear as day, hence the need to block. Sand the area until an even finish of base is all that is left. View Related Article
