Our most advanced, pure synthetic hydrophobic wax.
是的，所以不能用水珠的形态来判断。是否要打蜡应该用美光网站介绍的方法，洗车后用手指划过漆面，如果吱吱声就要打了。
另外有些封体是几天内有水珠，几天后就没有了，有些发文说打鲨鱼会出现这种现象，这应该不能认为保护性没有了，而是蜡的性质是如此。
How do we measure or test how well our paint is protected? All types of protection create an invisible surface layer that repels water and contaminants. This water hating or hydrophobic layer causes water droplets to either bead up on or sheet off of the paint surface, depending on the type of protectant in question. Natural carnauba wax finishes are extremely hydrophobic and tend to repel water more strongly than synthetic polymer sealants. As a result, it is usual for waxed finishes to bead up strongly in wet weather, with water droplets literally appearing to be pushed upwards off of the paint surface. In contrast, sealed finishes tend to be much slicker and less hydrophobic, meaning that water droplets don't tend to bead up as much but instead run off quickly and freely. Both of these characteristics are indicative of a high level of paint protection. In contrast, if water just sits on your car without beading or running off, then the chances are the level of protection is low.
