A few leasons I learned when I stripped my DA tac squads to turn them into smurfs.

If you have a heavy hand with the brush (like I unfortunatly do) you are probably not going to get all the paint of without a LOT of work, even using simple green. But you will still get enough off to reprime them.
If you prime your sprues before you put the models together there is a good chance that parts will fall off when you take the toothbrush to them.
Plastic models float. Weight them down with a nut or something while you a soaking them
