This is a 6ml (0.20 fl. oz) bottle of Z-42 blue Thread Locking adhesive from Pacer Technologies. If you race Nitro vehciles, you will need lots of this stuff to keep any metal on metal screws from vibrating loose. Best preventative measure you can do to you car is to make sure screws are locktite'd down, so you can finish those long mains! Blue thread locking adhesive is not permanant and will not permanently bond the screws. If you are having a hard time removing thread locked screws, use some heat from a heat gun as thread lock will break down under high temperatures.
