I just used an LC Hydro-Tech pad on an F-250 4 door today. I was super impressed with it and will be ordering more. I loved the way it held up during the entire detail and didn't become saturated with product. After each panel, I blew the pad out with compressed air. I was using Meg's M205 and the LC tangerine pad. I also used very little product as a result of the pads.
Usually I use several pads during a detail due to the pad becoming saturated with product. I always clean on the fly, too. This pad stayed firm, just like it was when new. The Hydro-Tech's will be my go to pad now.
I have some of the Surbufs, just haven't used them yet. I've heard great things about them.
