Not strong enough to get polish off...options?
 

Hi,

I've got an 84 diesel whom I love, her name is Cupcake. Anyway, the
paint is oxidized, the blue color. I tried to polish it before, and now
it has some white streaks. Really, I don't have the strength required to
really rub it off. I was reading a technique of applying Meguiar's #7,
several times, letting it dry, and really rubbing it off. I fear the same
thing would happen. Is there something I could rent that would do
this, or any way of doing this?...I'm not a total weakling, but was
surprised of how hard it is to really do a good job polishing an old
car.
Thanks
