I think the issue people are having is that rocks aren't hitting the car so to speak. The paint is falling off in the driveway, and if that is the case you are bloody right I am going to talk to the dealer about it.
No. The paint isn't falling off by itself. They sit in the box or the display shelf, which is the equivalent of your driveway analogy, and the paint remains fine. You drive your bindings off the lot and take it off-roading. Some of us jib, jump, and go rock diving. Even if we aren't doing those things, we are still constantly flexing these bindings putting stress on them all the while they continue to get rocked by vibrations.
So then the paint falls off and people think it did it on its own. Again, the paint stayed on just fine when it was sitting on the shelf or in the box. Not to mention getting shipped around.
Long story short? Who cares?
