Gravity RC extra high viscosity pure silicone diff putty
Gravity RC have introduced their new 20 million Cst pure silicone diff putty. The 100 percent Polydimethysiloxane fluid is recommended as an alternative to commonly used putty in gear differentials or other moving applications. The extra thick putty offers ultimate reforming properties and due to its viscosity it can easily be handled with no mess, though the package still comes with an applicator syringe as a bonus.
