Best way to remove chipping clearcoat?

The clearcoat on my '70 SDV is shot, it spent most of its life baking in the prarie sun. So much so that where the door handles cast their shadow on the door, there is still some clearcoat left. The top half of the car has only the Chateau Mauve (Purple) paint left or no paint at all, and the bottom half of the car has all of its paint still, including clearcoat. There is a line somewhere around where the chrome trim is in the middle of the body that the clearcoat has receded to. Suffice it to say I am repainting. Sanding the paint/surface rust is easy enough, but I'll be damned if I can find a way to get that clearcoat off. It is a painfully slow process to get through even a small part of it. Short of sandblasting (I dont have a sandblaster and can't afford to buy a good one, also I'd prefer not to pay for renting one since I am still in school) is there a better way (other than my current hand sanding/orbital sanding) to get this blasted coat off? By the way shes getting painted black. I contemplated keeping her all orginal but I think it would be too expensive overall. Seems like everyone thinks Chateau Mauve is such a neat colour except me. The interior is a matching colour, whatever it is called and is cloth. If I ever get to redoing the interior it probably wont be purple anymore but for now it'll have to do.
