I know Carnauba Jett can be a little trick to use and mixing it 1:1 with OCW makes it about as easy as OCW to use. How does this mix benefit OCW? Better looks? Durability? Thanks!
The main thing for me is that it makes Carnauba Jett a lot easier to use, like you pointed out. The additional carnauba content of CJ gives an even deeper look to OCW. Durability seems similar to OCW.
I've added FX-100 to this mixture recently. I took an empty 16 oz bottle, added 40% OCW, 40% CJ, and 20% FX-100. I was looking for the added gloss that FX-100 produces. The "Optimum Jett 100" works very nicely after washes. Easy on-easy off. Some added "wetness" as well.
