yes you can ruin it! i see it all the time, even dealerships - they use cookies or abbrasive disks on a rotary sander. the best thing you can use is a razor blade or very sharp scraper. of course, dont dig into the block... youll get use to it.
another good idea to use is sandpaper (240 or higher) on a softblock or on something flat and stiff.

plastic scraper/razor blade for the big stuff, then scotchbrite and elbow grease. I use those rotary sanders on air tools to take down hard *** weld slag, so if your not carefull you can **** up aluminum in a hurry.
