Pure Silicone diff Putty 20,000,000 cst (20Million)
GRC420 is 100%
Polydimethysiloxane fluid, and is recommended as an alternative to
commonly used Putty in gear differentials or other moving applications.
This New extra thick silicone putty is better than conventional putty do
to siliconeÃ¢€â„¢s ultimate reforming properties. Unlike its sister
silicone's it is so thick it can easily be handled with no mess, though
the package still comes with an applicator syringe as a bonus.
