[6pack] [6-pack] Undercoat removal

[Alex]

I used the wire brush on a grinder also. Did a great job. But even better 
are the purple 3M grinding disc that are about 3" in diameter, 1/2" thick. 
You get these at a good auto paint supplier. They work three times as fast 
as a wheel. The only drawback is you cannot hit too many screw heads, nuts, 
or sharp objects as they will deteriorate faster. On areas like inner fender 
wells, and engine compartments they can't be beat IMHO. They are not cheap, 
about $4-$5/each and come in a bag of 3 if memory serves me. Same advice for 
the gear to wear. I added ear protection.
