You assume the bond is mechanical completely...think nail in wood..

What about chemical bond? think glue and think water spots.....

And/or combinations of each... think Nail gun where nail has glue on it.....

the question for each wax/sealant is how is it bonded......

most likely a combination of both mechanical and chemical....

there has to be a point where layer does not exist as applying more product removes underlying product since forces holding product are not sufficient to hold it there due to rubbing action of detailer applying and buffing.....
