When to use a Flannel buffing wheel vs. a UBM buffing wheel
Brian Arthur of Centex Polishing and Kevin Clapp of Texas Premier Polishing discuss when to use a Flannel Airway Buffing Wheel vs. when to use a UBM (unbleached muslin) buffing wheel.
In most cases, you'll want to use a flannel buffing wheel when you have surfaces that you may need to work around, such as valve stems, buckles, brackets, etc. as the softer nature of the wheel will work its way around those obstacles/objects.
UBM Airway buffing wheels are more often used on flatter, simpler surfaces where working around things are less of a concern, such as diamond plate.
