Ever since I've polished the windshield with that LC glass polishing pad and used Einzett Glas Polish thereafter following a car wash, I've never had to worry about using anything like RainX.
Even in total downpours with big raindrops, the water just turns into tiny beads and I only have to ever use the lowest intermittent setting. 60mph+ on the highway is even better...don't have to use the wipers at all.
