TO HAVE A STRAIGHT BODY PANEL ON A CAR YOU MUST USE A LONG STRAIGHT SANDING BOARD........ UNFORTUNATELY THIS CAN BE QUITE TIRING, AN AIR BOARD TAKES THE WORK OUT OF THE SANDING .............THIS BOARD IS ALSO A DUL PISTON BOARD, DON'T BE CONFUSED WITH THE CHEAPER SINGLE PISTON BOARDS...... 2 PISTONS PROVIDE A MORE POSITIVE PUSH PULL ON THE BOARD @ 2500 SPM FOR RAPID MATERIAL REMOVAL WITH NO DEAD SPOTS.........THIS IS A VERY GOOD QUALITY TOOL AT A REASONABLE PRICE. NOTE : THIS TOOL MAY COME IN EITHER RED OR MILL FINISH .THE MANUFACTURER SENDS THEM TO US BOTH WAYS
