that link is to .com...need to pay duty/vat etc on that?
one day i will find something that shines that works for the tubes.
i did apply something silicon based once and it looked amazing but won't help in future in case of repairs so i stripped it off within 24 hours when i twigged.
i have in my rib cleaning box about 5 bottles from various makers and they are all crap to varying degrees, some are downright not fit for purpose as a "polish" unless streaks is the purpose!
i do giggle at the some of the bottles when they say "buff to desired shine". it should read "you can buff this down till cows come home to no effect"
