Well it's been a little bit more than a month that we've been using the thunder and lightning and without sounding like commercial we are very impressed with the results received. It looks like when the products are mixed on the car between the two presoak arches it seems like there's a reaction going on the surface of the car and you can see the dirt lift off. Also We are doing a much better job on the stubbern road film that's tough to get with touchless. Cost per car is in line with other products we've tried. Bottom line cleaning results are more important and I think we found it.
Thunder (low ph) titration 1% dwell time 25 sec then Lightning (high ph) titration 1.5% dwell time 35 sec. We also hit it with a low ph foam just prior (3 ft) to the Axis High Pressure Wash to bring the ph back down and we get great water break on the car.
