Using a soft bristle brush, while washing the car, will be equally ineffective. A soft rag has to be used during washing to get that car clean. We found the same rag method was necessary when washing all the sanding dust off our boat in between sandings and fiberglass layups or more puttying. So following the Coppercoat directions might not be the best method for some boat owners. Just relying on wiping down with clean paper towels, or very clean rags, and alcohol, I felt was not enough.
While residual dust might interfere with adhesion, it wouldn't have any bearing on antifouling performance.

If one doesn't follow the manufacturer's explicit instructions, then what recourse does one have with the manufacturer?
