This is the block of concentrated friction modifiers for the Rex Black Diamond wax.
This is not to be used on its own, but with the BASE BLOCKS included with the Rex Black Diamond Wax.
Rex Black Diamond Wax comes with one Modifier Block and 11 Base blocks. This enables users to make a wax blend with a high concentration of friction modifiers by using less Base Blocks as part of the mix (ie one may use 7 base blocks instead of all 11, or they may use 4 Base blocks etc).
For those running a higher concentration mix – this Modifier Block is to enable you to make further blends with your remaining base blocks.
For full information on the Rex Black Diamond Wax refer to that product here.
And this can also be purchased in a bundle pack here.
