Hi Monikieman,
The Nikwax spray, is like a very light version of the wax on wax jackets. It doesn't leave a waxy residue. On its own, makes the material water repellent (a bit like the G1000 wax), but, when combined, they seem to work very well. My jacket is still soft but has a light waxy sheen now but it keeps me dry.
Also, to save money, i make my own version of G1000 wax. Just paraffin wax (90%) and bees wax (10%). Easy to make, just melt together in a bain marie and let set. Done!
