We had a really great thread on this topic in my paint FB forum, but I cannot find it!
Before you buy one, make sure you check out the battery powered ones. The technology of the batteries has come a long way & a lot of the painter have gone to them even for buffing. I cannot put down my go old Makita variable speed yet, but am going to buy a small battery powered orbital for getting into small spots. The Milwaukee is supposed to be one of the best . One advantage is of course NO cord...Even someone who has painted, wet sanded & buffed more than 100 cars over the years, still grabs a cord now & then!!!
Depending on if you are just applying wax/ polish or actually buffing would determine whether or not to buy an extra battery. I would think you could probably polish a GTO on one battery. I always like to have an extra battery around charged up just in case.
God bless
