I really like the look of the tires, not too glossy. Did you buff the Z16 after application to get it to look that way?
I have yet to find a tire dressing that is matte enough for me to not have to buff, and if this Z16 is that matte with no buffing then I am going to have to pick some up!
Cars look great, and by the way how did you like the p21s
gel wheel cleaner on the lambo rims? I usually just use car soap on clear-coated rims for fear of damaging the clear, but if you have had success with the gel on those (obviously cleared) rims then this gel must be pretty good.
