Pros: Shiny smooth edges
Cons: Takes effort
This is the prep for using Metal Jet, makes edges smoother, faster. Used by euro racers.... You need the pad to rubb it on. Takes some muscle power Edges are shiny afterwards. Do not forget to clean the edges with a clean cloth.... You will be amased how much dirt is coming of. On Snow it seems to do its job well, less tugging on the edges.
