On the side, the effect is quite outstanding: As the disc is almost dry even at low speeds. This is especially an advantage when the side window with downloading or re rauffahren brings filthy wetness that has collected in the disk box in the door. On the rear it works well with my sedan with notchback, the hatchback contrast injected due to design necessarily all the water behind the car up again, so that the rear-window wiper must be still now and then operated.
Well, I recently used it sometimes to parts of my windshield. I have the passenger side to just above the center where the dashcam mounted, sealed with Pearlway. The driver's side, however, is unsealed.
The video is quite nice to see the difference: The left third of the image can be seen how the water forms larger areas, while on the right smaller drops are formed. I deliberately selected a section of highway in which I start from scratch after a construction vehicle, then accelerated up to a speed of 80 to then having to drive to the circuit in the built-up area back under 50 kph. - I have a little cut together so that it meets the 100-MB limit of Amazon video.
The rain and the water of driving ahead or oncoming vehicles begins with me only when Tempo 60 being repelled. Then, the view on the right side is better. At lower speeds, however, I feel the unsealed plate side left as enjoyable. But this is certainly a matter of individual perception.
On the subject of application: As a lot of solvents are probably in it, as you can tell by the smell. This means that Pearlway must be processed fairly quickly, because otherwise it evaporates already in microfiber cloth. Consequently, I can only process small areas with economical application, otherwise it will be uneven. Even the polishing is a debilitating issue - compared to conventional wax for the paint, I need at Pearlway always two or three polishing hallways until I really get polished all gray areas with quite high pressure.
On the positive side, the fertility and functionality. One star deduction is available for the not quite easy to use.
