Vaughn had not held out much hope of finding an interference-blocking material. It was practically like looking for a needle in a haystack, and Fred and George were only two people, after all.
But he had clearly underestimated the twins' abilities. George might have said Fred was wasting his time, but Vaughn knew perfectly well that he had definitely been involved.
