I put a nano-coat on my paint, and my windshield. The nano-coat makes it effortless for wipers to remove stuff. Outside of winter, I never use my wipers...literally. I only used my wipers once since I got the car, last week. At speed, stuff just slides off. It's the next step up from a product like Aquapel or Rainx. Although my friend is the distributor and I get this direct, and at cost, you can get it through select dealers. Here is a video of the stuff self-healing your paintjob if someone keys your car:
