I use a 2 pounder on those peskey BBS wheels on BMW's. Suckers will stick 4 out of 10 times. However, do not do like my trainee did on my car. Install a lug loosely, NumNum sent one of my wheels off the car, out the shop and it bounced off the building behind me. Whoops, glad it missed anything important.
Rubber deadblows are also handy for breaking intakes loose, knocking stuck axles out of the cups, knocking oil pans loose, popping the lower plastic trim back onto 3 series Bimmer, and in general knocking things around you dont want dented up. We call ball pien dents elephant tracks. I've also used them to knock extension housings off, diff covers and stuff like that.
