Why I am ditching my favorite sealant (Polymer Net Shield) for CQuartz UK. Is PNS flawed, or is it just me?

I don't know regarding the availability of it in USA, but Sonax Nano Lack Protect is pretty good stuff, I believe it is stronger than PNS.

It states a durability of 12 months.

A bit off topic, but a sealant that really amazed me, regarding durability, is PolishAngel Viking Shield; I used on wife's car, and it is going strong after six months, and her car is bombarded daily by bird bombs, she parks under the trees at work.

Best regards.
If this is the Sonax Nano Paint Protect its a good product but you still have to top the coating with Polymer Netshield every 2-3 months.

I've used:

CG HoneyDew
DG901
Optimum Car Wash
Meguiats DUB Car shampoo
D114
Poorboys Spray & Wipe
...and even Mothers Waterless Wash & Wax with no ill effect.

In addition to this list I have used

Optimum No Rinse
Optimum No Rinse with wax
Meguiars Hyper Wash
Sonax Car Wash
