Help removing door guards (rubber strips)

[tasattack]

Im in the process of removing the rubber door guards or strips from my 95 neon after the drivers side decided to pull away from the car, i removed it. but my question is this, does anyone know an easier way to remove the adhesive backing from the door itself with ease, or is this a project to do a door at a time because of the lengthy process of adhesive removal?

I buy adhesive remover wheels from my local paint store. They are used in a hand drill and are made of a soft plastic, they just spin the adhesive off without nicking or scratching anything else, not sure but I think they are a 3m product.works great and quick.
