The coating thats used in it can cause damage to the wiper system, sensors specifically. Plus you pay about double for it and it doesnt work any better than the dollar stuff you get at the gas station. I put a jug in my camry and it didnt work well, smelled very strongly, and seemed a waste of money
I agree, I used Rain x a few years back on my A8 and the dealer had to replace the unit and told me to avoid using Rain X fluid
