I want to apply
Rain-X a water repellent to my windshield. To make sure the glass is clean first I'm going to run the car through an automatic car wash.
- I assume I want the cheapest external wash with no added Clear Coat Protectant or Tri-Polish Wax or other superior Premium add-ons which would coat the windshield before I added the water repellent: True or False?
- I assume that after I've rubbed on the water repellent (and let it dry) I can then run it through the car wash with their high quality sprayed on wax and/or coatings and that won't impact the repellency of my water repellent coating: True or False?
