the bottle is TINY but a little goes a long long way ive had my bottle about 3 years now and only half used
it might not be the best stuff in the world but i like it a lot i use those little make up applicator pads.. to apply stuff like this it makes it far more economical which can be had from the birds section in most super market / boots.......
(or i beg my sister for a few as you would look a right poof buying them in boots )

but be warned theft of said applicator pads is no acceptable apparently some of this face slap stuff and accessories ((she did have some lovely foam pads)) are very expensive only this was explained to me in a bit of a rage ...... Still cheaper than most "detailing suppliers" however
