Sand Blasting Car -- what would you do?

I was kinda thinking the same thing doing both sanding and blasting...still not sold yet.

What I was thinking was hit the large areas with sanding and then hit places that sanding is a ***** like window window trough areas, deep seams, undercoated areas, etc with the sand blaster. But then parts of me say sand blast the crap out of the whole darn thing....
