For a maximum glossy finish, Meguiars tyre gel cant be beaten. I havent got enough fingers and toes to count how many products ive used in 16 years but megs tyre gel is real glossy. You will never find a product that will last ages on tyres due to centrefugal force when moving, gravity etc forces the product even when dry so fling is always enevitable. Zaino Z16 or Finish kare top kote are both excellent, both water basis but need layering. 2 coats looks immense.
