A weld line in a flat panel will form a valley (I think Robert covered that), so once you grind the welds down, you'll probably have a bit of filling to do. If you can't get a regular dolly behind the panel, maybe you can sneak a spoon up between them to use as a dolly, that can help minimize the "valley" effect.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
