You folks who are getting "holographic effects" that are *NOT* true, rotary-induce holograms are lucky, especially those of you with Audis!
With all the different variables- your water, your LSP, the dirt you're cleaning off the vehicle, your wash technique, etc. (and similar factors when QDing) it's not unreasonable that *some* shampoos will work better than others. If [whatever brand/product] doesn't work for you, I'd say to just try something else. Like any other detailing product, it's not like everyone has to get great results with every product.
It occurs to me that with #34, the alcohol content might be softening the LSP.
