Have used this product for the past two years now, and in forty years of owning cars, this is one of the best products i have come across. The wash gives good lather and cleans the car without residue. It rinses off well, and the polish is the easiest polish to apply. A small amount on the sponge applicator, and wipe it as thinly as you can across the paintwork. Do not 'rub it in', but smooth it thinly over the surface. It dries in next to no time, and polish off with a decent quality cloth. The finish is excellent. (If you have a black painted car, the finish is mirror like). Not the cheapest out there, but well worth the money, and it still beads water weeks later.
I bought this package two years ago. During transport one of the bottles leaked. Amazon replaced it with a new package and i could keep the broken one. So now after two years i'm still using this package.
