ProTek RC Blue Thread Lock (Medium) (0.34oz)

ProTek R/C Blue Thread Locker is a medium thickness, medium strength formula that provides great resistance towards shocks and vibrations, yet still allows hardware to be removed and disassembled with hand tools. It is a must-have item for 1/8 scale use, 1/10 scale use and especially any vehicle or aircraft with a nitro engine. ProTek R/C Blue Thread Lock also helps to prevent rusting of threads. 

For use, simply apply the fluid to the threads of your non-plastic fastener or nut, and tighten. In the absence of air, the fluid will start to cure in about 10 minutes, with a finished full cure in about 24 hours.
