Had a chance to use the NanoSkin Hydro Express this past weekend and had a decent thunderstorm yesterday on the way home from work and snapped some pictures! Fantastic beading and the process itself couldn't be easier. The beads on the vertical panels were tiny and streamlined. I am very pleased with the results you get for the 10-15 minutes it takes to apply it, with a life of around 2 months it's perfect for when you don't have time to wax, or if a customer is in a hurry.
I've been using Hydro Express for the past few weeks on my own car and customers cars, so far very impressed. I think it leaves a beautiful slick finish and the beading is well above what you get from most QD sprays, very solid product so far!
