Got sidetracked with a powerwash breakdown.
When I finally got back to the car there was terrible spotting
from the sun cooking on the deck lid and hood.
Looks like the clear coat is etched
Tried meguiars wash , detail spray , windex , vinegar ect.

I have a ceramic coating and XPEL on my C7 so that doesn't happen. Dried mineral deposits don't stick on those surfaces.

However, on other cars I use a liquid carnauba wax, and a little light pressure. The spots are not etched clear coat, but the dried mineral deposits are bonded to the clear coat and often require more than detail spray to remove.

If it's hard water deposits then vinegar and water will remove it. You might need to soak for a few minutes under a wet towel.

Thatwas my goal ,,, to get a coating on while the car was still new .
Just ran into a little speedbump .

I've also used some 3M Imperial Hand Glaze to take off water spots.

Short story: I have a ceramic coating (cquartz finest) and got water spots that I couldn't wash off. Neither could my detailer, even with vinegar. He ended up having to buff the panels that had the spots and reapply cquartz finest. So, having a coating won't necessarily save you, but you will have extra layers of coating to work with.

Longer story: On a hot, sunny day in bumper to bumper traffic on a freeway, I drove slowly under an overpass with water pouring down from it like a waterfall across all lanes. Was annoying, but didn't think much of it. Drove the remaining two hours or so in traffic and sun in my black car. Didn't wash it for two days. (Washing it that day might or might not have saved me.) When I did wash it, the spots didn't go away. At all. Took the car to my detailer who couldn't get the spots off either. Worst he'd ever encountered. We suspect they were cutting cement on the overpass, and the runoff water had loads of minerals. He buffed the (horizontal) panels on the car that had the spots -- maybe taking off half a layer of the ceramic coating -- and reapplied 2 layers of cquartz finest to those panels.

I just got the car on Wednesday , Did the Bowling Green Plant tour
and Museum on Thursday then drove home to Kansas.
My very first task once home was to get the coating on.

I recently read that distilled clear vinegar is the way to go on this. I suggest that you do a test in a spot that doesn't matter before you go full out with this product.

isopropyl alcohol or a clay bar, either will get them off.

indyblue98

Beginning to think it must be the soap and not the Water thats making the spots.
Been trying all the above suggestions ,,, still not going away.

Keep the ideas coming

Thunder22

even a clay bar doesn't work? if you can't get them off with a clay bar, I would stop trying anything else and take it to a detailer.

just my .02

Update:

Got some "Cleaning Strength" Vinegar .
Added some Cascade Spot free rinse Dishwashing stuff.
Letting it soak like 15 minutes then Meguiars detail spray.
Seems to be making progress... lighting can be tricky, but thats
better than before.

Will post results in a couple hours.

If you don't get the results you are looking for try this:

I have CQuartz Finest on my car but I recently purchased a CR Spotless water de-ionizer and have to say it is pretty amazing. No matter how well I would dry the car with a blower and microfibers I would always have waterspots the next morning on my side skirts and on the rear valance that is carbon flash. Now with the CR Spotless system I don't even have to dry the car if I don't want to and can let it air dry with no spots.

Depending on when, and if you're going to ceramic coat the car, you might as well start at the top of the process and work your way through. Unless you were going to have somebody else apply the coating for you.

1: Wash it
2: Clay bar or mitt
3: Polish
4: Paint prep
5: Ceramic coating

If you're going to do it yourself, you need to clay bar the entire car to remove all the contaminates before you coat it anyway.
Then move on to the polishing phase. This should remove the spots. If not, depending on you equipment, and your degree of comfort working with different grades of polish, is where you need to make the decision to take it to a detailer or not.

Good luck, it's gonna look great when you're done!

I deal with it in Florida all the time. Probably worst place for it.

Any one of the numerous paint cleaners and or swirl removers will work with a medium grade pad on an orbital buffer will remove the spots. You will essentially be doing a paint correction and it is hard work but it does work.

I have used the alcohol and it works

indyblue98

85-95 % gone at this point.
Looks like I Still have some work before its ready for the Ceramic Coat.

Thanks for All the replys.

If you are having a detailer apply the ceramic coating, just let the water spots go for now. The detailer will be buffing the heck out of your car before applying the coating. Your car is going to look great.

Believe it or not but letting it sit out in the rain for a little while will remove every spot.
