Black Diamond Tyre & Trims

ODDLY, this claims to be an ‘exterior trim and tyre polish’. We detected no polishing action, although you do have to work the clear liquid into the tyre after spraying. More timeconsuming to apply than our aerosol favourites, but it does give more control and reduces wastage. It was a clear step behind the aerosol, yet was still working and is our pick of the trigger sprays.
