danlc- I bet the M101 helped immensely

Yeah, good point about how there weren`t many good (i.e., aggressive + nonrotary) products back then, though I never had good (i.e., timely

) results with M105 either (and yep, had plenty of advice from guys like Kevin and Barry). Just took too long, even with 4" pads, compared to my results with more aggressive machines. Did a direct comparison a while back between my PC/3" and my 3" GG pneumatic, the GG killed it.
(Not liking rotaries after my work at the dealership, I got a Cyclo that I still love, my "older one", but it wouldn`t accomodate the Jag`s curves so I got a PC...*?!?WT#?!?*... it simply didn`t do much of anything compared to the Cyclo and that was on ss lacquer! Even took it in for a look-see at the local repair place, figured something was wrong.)
Maybe I put extreme emphasis on "timely" since I successfully corrected deep fingernail scratches behind door handles *by hand* back then, which might be comparable to the 1500 (wielded by an amateur) on the Chevelle.
