If a product has ANY glaze properties, it IS hiding SOME damage. Period. In your case, most likely it's buffer trails from the wool pad.
So are you acknowledging an awareness that after that 3-4 week period, some of the damage you "removed" may come back as the glaze properties wear off?
Just trying to get to the bottom of what you're actually doing, or at least what you think you're actually doing -- this has been the point of contention all along here. If you recognize that by using a product with glaze properties and finishing with a wool pad that is not held flat to the paint surface you're leaving damage behind that will eventually show up, then the problem we have is that you're misrepresenting your work by saying all the damage is "gone." If on the other hand you don't recognize that you're leaving behind swirls/trails which will eventually show back up, please allow us to educate you and try to help you improve your technique so that doesn't happen.
I realize it is the nature of dealerships to only care that a vehicle looks good long enough to move off their lot, and thus that is the standard you have to cater to in your chosen line of work, but hopefully you realize that is exactly what you're doing. People other than overspray companies may see your videos, hear you say "all the damage is gone" and assume the buffing technique you demonstrated is the proper technique for actually removing damage, when in point of fact it's just hiding a certain amount of the damage. Later these folks come to those of us who specialize in paintwork correction wondering why their damage came back after trying your methods on their own.
I would just urge you not to mislead viewers in that respect when creating videos -- let them know at the very least that there are extra steps involved that either aren't being shown or aren't being performed to get the results to actually last because of the type of business you're in and the outcomes your customers expect and require.
