Prima formulas are unique compared to other detailing products on the market. Great lengths were taken, and no expense spared, in order to create a family of car care products second to none. Thoughtful design even went into the packaging. The bottles are short and wide for a reason. A solid base and low center of gravity means you are less likely to tip over your glass cleaner as you reach for your QD. If the makers of Prima put this much thought into the package, imagine what they did with what goes into each bottle.
