Next, we envisioned anartklc full of charts demonstrating how different these sanders arc. But as testing began, wc discovered that each sanders does the job it is supposed to do. Lach one sands.1 surface smooth and flat without leaving huge swirls.
What we found to be the most important aspects of these sanders were attributes that do differentiate the tools: How the tool fus your
