There's no need to wash your car first, just spray on, wipe with one microfibre cloth to remove the dirt and use another microfibre cloth to buff to shine.
Very good product been using it for a long time very good quality . I think all the Car wash should try.
order delivered very next day even one of those items was missing and they found and delivered next day
Easy to use gives a very slippery feel to paintwork not so good on glass had some smears show up when sun was low would use again at right price.
