Raceglaze wax?

What's the difference in raceglaze 42 and 55?

 

The amount of carnauba.

 

And the durability. 42 should last 3-4 months while 55 is about a month or so more.

 

Ok cool ill be getting a sampke of 55 I think

 

So RG55 cost more than RG42, but less durability with more nuba?

Is there any advantage the RG55 have over the 42?

 

I think Ken meant a month or so longer than RG42.

 

Oops, I read it too quickly I guess
