“We've wasted a lot of time trying to eliminate thickness variation from our sanding machines. After
PRG performed a variety of repairs, profiling, grinding and balancing — precisely to our specifications
— the finished surface on our contact drums show a variation of less than .002 inches across a 116-inch-wide
panel.”
