If you have tint for windows then it has a clear backing on it. You must peel off the backing to expose the sticky side. Soak the sticky side with the soapy solution to prevent everything from sticking to itself. Also make sure the thing your sticking the tint to is also sprayed. Don't use too much soap in the water either. it just needs to be a little soapy. A credit card may be too harsh to put the tint on with. It will scratch it. Try using a semi hard glazing putty applicator (the black squre rubber ones). Good luck.
