[6pack] undercoat removal

[Colin Thom]

The 3M stripping wheels are the best but you pay for the privilege. And,
don't forget to buy the mandrel you'll need to fit in your drill chuck. If
you've already got an angle grinder then Vance's idea is a good one but if
you don't have the grinder and don't particularly feel like owning one, then
the 3M wheels will make you smile..and they're faster than a twisted wire
brush, anyway. Colin Thom '75
