hi there,

im interested to try one.. but if u dont mind, i would like to ask u a question. ive tried a few products before, all a liquid form, not like yours, once applied, the windscreen will look like new. no watermarks at all.. but after 1 or 2 days, the watermarks was visible again. it looks like the product is actually not "cleanse" the watermark. it makes up "another layer" on the glass. once the layer gone (heat, wiper, or even water with auto shampoo), the watermark are visible again. how about your antirain?
