Has anyone ever used a product called Astro Shield on your car, If so is it any good?

it's an excellent product but it's a cleaner wax which means you have to apply it very carefully or it will streak.What happens is when you put it on and take it off you tend to rub harder in some spots than others so those spots come out cleaner giving it a streaked or mottled appearance.Personally I prefer good ole raindance easy to apply and leaves a great finish
