I put four windshield coatings through the only test that matters: time. Over 8 weeks I ran Soft 99 Glaco Ultra, classic Rain-X, GYEON Quick View, and Ethos EZ Glass side-by-side and checked them the same way every time—beading, sheeting, wiper behavior, and how they held up after real washes and real weather. No “first day” hype, no one-week victory lap. If a product falls apart by week 3, I’m calling it. I also show the prep that makes or breaks any glass repellent: proper cleaning, polishing if the glass is crusty, and using the right towels so you’re not chasing streaks and lint. Then it’s just consistent maintenance and letting the results speak. By the end of the 8 weeks there’s one coating that stays clearer, sheds water faster, and keeps the wipers happier—while the others either fade, get grabby, or just stop impressing. If you want a set-it-and-forget-it windshield coating, this test makes the choice pretty obvious.
