Just like my experience with the slickness of #26. Sometimes, slickness is down to almost 0% just right after the first wash and just as when you had dried the surface.
However, a day after that wash, or after it has completely dried from the wash, slickness is retained to atleast 60% from the time it was first applied.
I guess this is a fact and applies to all waxes, synthetic or carnauba.
So in that case, the beading may return a day or two after that wash. Seems like you had just removed a layer of contaminants that's why it's not beading.
