Tried Spray & Wipe for the first time last night. I had just washed the car for the first time ever with QEW and wanted to compare S&W to #34. Did a side by side comparisson on my hood. Poorboy's S&W was way slicker feeling than #34. I was quite amazed. When I went from using Mother's Showtime to Final Inspection I never imagined I could find a better QD to use. Looks like I might just use my #34 for claying and to mix with QEW now. Has anyone else used this product and liked it? Any long term differences between it and other QDs? I figure if I'm this happy with it, there must be some kind of a catch.
