I would be carefull with this stuff. It can be messy. In the event of a broken or split nail, you might try a piece of plastic nail, cut and curved to shape and stuck down with Superglue. To prevent hooking, file the edge of the plastic so that it blends smoothly with the surface of your real nail. These are created from a mixture of acrylic powder and setting liquid.
Acrylic can make a very nice nail which sounds good.
The main problem is that when it peels off, you will find your real nail surface has weakened considerably. This means you have to wait until strong new nail grows out to replace the weak part. The playing edge of the nail should be kept smooth and free of any rough spots. Use emery boards for bulk removal and progressively finer grades of emery paper for final shaping. It's always wise to test how it feels on the string as you reduce the nail length.
