I'll have to try that wool/M105 should I ever have to do another really marred up vehicle. The way you can spur wool clean oughta work great with M105 now that I think about it.
I tried the Cyclo (same wool used for Edge pads) wool pads with some other products and they didn't work to my satisfaction. With 1Z Pasta Intensive I did *much* better with foam cutting pads...surprised me, to say the least.
Unless you're working with something *known* to be Cyclo/wool-friendly I'd stick with the foam cutting pads.
