i see brother you are very experienced with the detailing products. i am not.
the interior was totally dry. really dry. the car had been standing for more than 6 months. what you see on the dash is a polish. it is left to dry overnight and it gets absorbed. remaining is taken off with a cloth.
as far as the seats are concerned, the front seats are worn out. the leather is highly dry. it will take some time to bring some shine and softness back to it.
the point was to initially clean the interior. not to make it sparkling new. it wont be possible without repeating the process 2-3 times.
now the car is on road. things will get better slowly and gradually.
