Comments on CQuart finest. The costly part is the paint correction. Of the $950 I spent only $275 was for CQuart, but as long as there's any clear coat the vehicle and plastic will have NO blemishes, at least in Wills' shop. Then coat it. Then just wash... Don't apply anything ever as it will dull the shine (if you do it can be washed off... Even waxes and sealers won't bond).
It is far beyond any sealer or wax and can only be removed mechanically. They warrant it for 2 years, but users I know who have had it as long as 4 years still rave. As far as being hydrophobic (run off angle is < 10degrees) and besides being chemical resistant (gas and bird bombs won't etch it even after a week on the surface)... Nothing sticks to it plus it is anti static so very little dust will stick.
The pick you showed is no problem. Of course, you can scratch any surface, but my car looks just like it did after Wills was through. The biggest trick is no touch washing... Do tires and wheels gently with dedicated bucket/MF tools and rinse first. Then, including tires and wheels) Rinse with pressure washer-> use foam cannon and let it sit for 3-5 min.-> rinse with pressure befor it can dry-> blow dry with a dedicated electric leaf blower ($30-$40) and then any touch up with a thick MF towel using no pressure.
If it needs touch up let a CQuart certified shop like Wills' wash and apply Renew (can be done every 3-6 months at a fraction of the cost). Pinstripes can happen, but since the coating is up to 100 times the thickness of your CC, your paint will be preserved.
I'd do it again in a heart beat. The paint and plastic still look look like new auto glass and no scratches yet.
Lay your head down and look at your finish toward a light or in the sun... You'll see the scratches and spiders. The flatter the surface (scratches are irregularities) the deeper and more reflective the finish.
Sorry to sound like a salesman. OptiCoat is a little harder, but most feel less reflective. If you have any more specific questions let me know.
