My car is opti-coated.

Had to take my car to the dealership to have it checked out for an error message. I asked them not to wash it when they were done.

They freakin washed it and left it out in the sun to dry.

My car is Black Sapphire Metallic. And now it has hard water deposits all over it!!!!

I've read where some folks used a vinegar and water solution (sounds like a douche commercial) to spray on and wipe off to remove the water deposits.

Anyone know if this would adversely affect the opt-coat?

If not, what is the ratio of water to vinegar?

Thanks.
