Doug,
It sure looks like wicking...are you 100% sure it dried in a few hours? Any chance (because the Snake Oil doesn't have the same foam as
Releasit DS that you were previously using) you were leaning heavy on the trigger?
Snake Oil has a 400sq. ft. per gallon RTU coverage, if say you were averaging 250-300 per, I would say cut back the juice and dry pass each wet pass and stay on that rotation.
From the "wet, during pics" it appears the snake oil cut a path just like other encaps if not better, like you said, it did "look" pretty good a that time, it was just during final drying it looked splotchy.
What were the HVAC conditions, ever had any drying issues or ventilation issues before?
Also, I don't think you needed more than 2 oz. per, and in fact If you made a "dry pass" to even out the shampoo I'm willing to guess you could have got the same visual results with 1.5 oz. per gal. So I don't think the chemistry is failing here.
We've had 20 guys chase a regular
releasit job with Snake Oil and have 0 issues. So I am trying to get to the bottom of your issue, cause obviously that was very embarrassing, and for that I apologize.
I can tell you what I would have been doing that Same night you noticed it. Running a synthetic bonnet like a Tuway and the sprayer of your choice and some 2oz. gal/snake oil and blending the area and adding some polymer in the process, keep in mind it would be a Blend and fix not a wet shampoo.
The soil level was high in some areas, but i don't think that was the issue on this job.
