Using a 15" x 2-3/4 to 30" Sanding Board on your car will help make the panel (fender, quarter panel, door, hood.....) that is being repaired look as strait and flat as possible. The trick is using the longest block that you can for the size of the repair so the whole area is sanded at once. This takes any little divits or waves in the finish sanding them and making the side of your car look as flat as glass. |
