I gave our 2006 MX-5 (very soft paint, it seems) a complete detail three months ago, finishing it off with Menzerna PowerLock. Looked great.
Fast forward to today.
- Two weeks ago was probably the last time I washed the car.
- After about one week of being outside collecting dust on the car, we had a couple gentle rain storms pass through a day or two apart.
- I didn't get to washing the car until a week or so after the the rain. The combination of dust and rain made it look awful, but I was sure it would all come off easily especially as it was rainwater and not hard water from sprinklers or something.
But no. After a thorough washing there are outlines of water spots all over the car. I tried FK425 with my plushest microfiber (remember this paint is soft) and it made no difference, only made the paint slicker. See below:
[As a side note, you can see the pattern of the water spots is not as I would expect of a highly rated sealant that's only 3 months old. It's my first time using PL. I applied 2 coats.]
So, my fellow enthusiasts, what can I use to remove the water spots without removing what's left of the sealant on the car? I really don't want to start over!
Clay bar?
