THE BODY BUDDY is that missing tool, you can check the curves or use it as a template for installing dash gauges, switches, locks etc.
The Body Buddy is light and durable (you know DURABLE when things fall onto the floor or get run over). Chemically resistant to common shop chemicals and will not rust or corrode.
Oh, don't forget the 3” scale by 1/8th's on one end.
And it's the top dog of body filler spreaders.
