I recently had a windshield stone chip on my RAV4. Unfortunately, I was able to book a time for repair in the dealership 3 weeks after the chip appeared, not sooner than that. I immediately after the chip appeared covered it with transparent tape to prevent dirt in the area of the chip. The chip looks like a star: there is the location where the stone hit and several <2cm cracks, so I assume it is repairable.
The solution of adding a tape wasn't however even a semi-permanent one. When driving in the rain and having to use the windshield wipers, the combination of water and wipers caused the transparent tape to fly off. So, I drove for some distance until I decided to put a new piece of transparent tape again over the chip. Unfortunately, according to weather forecasts there's a chance of slight rain before I finally have the time for repair.
Did I do correctly when I decided to cover the stone chip with transparent tape? Should I keep on adding new pieces of tape as old ones fly off due to water and windshield wipers? Or are they able to clean the stone chip area before the repair?
I have avoided automatic car wash before the repair because a car wash would almost surely cause the piece of tape to fly off; is this a correct decision?
