but he's been taking it through the car wash and also having the dealer wash it
In my opinion, the only safe way to wash a coated car is,
A: Careful hand wash by someone that cars and has knowledge of how to "touch" car paint.
B: Touchless wash
Here's my article on how to carefully wash a coated car, send the link to this article to your customer.
How to wash a coated car - The Gentle Approach for Washing a Car by Mike Phillips
Here's the deal.... anything abrasive that touches the coating is going to degrade it, that is micro-mar it. The more aggressive the "thing" that "touches" the paint the deeper the marring to the point of micro-scratching.
As soon as the coating is marred and scratches the water beading is going to diminish.
I keep the wife's Mercedes-Benz coated and after washing I do a touch-up with a either coating detailer or a coating booster and the results from my first-hand experience over time is
- The car stays clean longer
- The car washes faster
- The car dries faster
- The paint always looks glassy
The above are 4 of the primary benefits (in my opinion) to putting a coating on a car. But it all comes down to what I preach and practice and how long anything on a car lasts comes down to how you "touch" the paint.
Washing is touching the paint.
Also, just to add... in all my detailing classes I cover this topic in-depth, that is the topic of matching your services to your customer and a part of this is when detailing cars for other people the FIRST thing I ask the customer or potential customer is,
How are you going to wash the car?
And that is the most important question for both of you.
Seems simple and it is simple but how car paint looks or how long anything you put on it lasts all comes down to how the car is touched.
