I use modelstrip, and have done a few times. One occasion I just wanted to remove a tiny bit, and leave the rest (a bit of paint that went where it shouldn't). No problem! I've even stripped a 1/144 Sweet Macchi, with details so small you can barely see them, and clear too, and no problems. Just apply enough, put it in a plastic bag, and wash off some hours later, using a toothbrush. Easy!
