With the car going in and out of Veho's garages, I haven't washed my car - by hand - yet to tell you the truth.
Thing is, they wash it every time it's in.
Once went to a high pressure automatic wash place, and that's when I found out the boot was leaking.
I also don't have a place to wash it. Maybe next year?
Others here may be able to help you with that exact product. Never used it, you see. Meguiars products have been recommended by many here but I haven't found a store in Finland that sells them.
