I phoned Chafe Pro as I wanted to make sure the chafe gear wouldn't be so thick as to not fit in my chock; they told me the product is relatively thin and only grows the line diameter by 1/4" or a bit more. I also asked about the Norton warning you received; he told me they have had their IT provider look into it, the site is secure, it comes from spam but does not in any way affect customers going to the site. I trust that is accurate, sure hope so.
