Will Rain-X hurt a Cee Bailey's shield?
Now that is interesting..., I only use a 50/50 mixture of water and Hydrogen peroxide on my windshield. cleans great and gets all of the bugs off without scratching or discoloration. Just spray it on, let the bugs soak a couple minutes and wipe off with a microfiber cloth. Works every time.
The forumula for Pledge changed a couple years ago and it isnt as good as it used to be so I've stopped using it.buy a can of pledge (not the lemon, attracts too many bee's) spray on a rag wipe off. It is a wax and does a great job repelling rain, and even better BUGS!
I have used it for years
Works fantastic on chrome too. BUT!! make sure you don't spay it on the engine itself. It will "milk" the engine cast.
Spray on a rag, microfiber etc..
