Ceramic coat water spots - removing it with D140 wheel brightener - safe? recommendations? dilution?

[Gman87]

I applied CarPro cQuartz UK 3.0 on my car about 8 months, there are a few stubborn water spots that won't come off with vinegar and water 50/50. I purchased some D140 as I saw a few suggestions online this is a trick used by detailers to quickly and effortlessly remove these stubborn spots.

A few questions if you can help:
- Should D140 wheel brightener be diluted for use as a water spot remover? what kind of dilution formula should I use?
- Is D140 ceramic coat safe or will it affect the top coat of cQuartz?
- Any tips or recommendations for application I should follow? (e.g: don't let sit on paint longer than X, wash car before and after application)

Thanks

I would try Car Pro's Spotless first, as it was made to remove water spots and not remove the 3.0.

It appears you haven't used WB..do yourself a favor and stay away from that caustic chemical.

Wheel Brightener still has a place but I find myself using it less and less over the years. Knowing what I know now, I should have worn a respirator back then when working with it. lol

I also would suggest trying out CarPro Spotless. Worst case scenario is to use Essence to remove it. Essence has been used to repair fading coatings and I used it to remove a scratch from a vehicle coated with CQUK not too long ago. After the scratch was gone, I went back and buff out that particular panel with Essence and coated it again with CQUK. I am just anal that way since it was not my car.

Waterspots generally are much easier to deal with when they are fresh. Once baked in, I often find myself resorting to polishing it off.

•IMO:
-An AIO, such as Klasse AIO, is a much “safer”
product to use for water-spot removal from
CQuartz UK 3.0, than Meguiar’s D140 will
ever be—regardless its dilution ratio.

RE: Klasse AIO/“safer”
•won’t harm the UK 3.0 Coating
•doesn’t contain any Ammonium Bi-Fluoride
(ABF)
