removing tint is really easy, razor blade a corner (press the blade flat against the glass, so the entire sharp surface is against the glass).
Try to keep it in one peice, pull it off.
For the rear, dont use a razor. Use your fingernail, dont scratch against the heated elements, and use a ammonia/ethanol solution to loosen the glue if you're having trouble.
