From my understanding, Hydro2 Lite is a consumer geared product which is meant to be a "ready, set, go!" product rather than trying to figure dilution ratios etc.. Hydro2 (concentrate) can be used wet (most favored), dry (in the right dilution) and as a QD (again in the right dilution). I've watched the video of Hydro2 Lite a couple of times and surmise that the beading difference between the wet and dry application comes from the fact that taking a diluted Hydro2 Lite and diluting it even further by applying it on a wet surface would diminish the hydrophobic qualities.
Personally I am already set up for all dilutions and LOVE Hydro2, so this product won't replace anything in my arsenal..... and if I want a QD, I will just use a dilution of Reload (which has served me well in the past)
