Well it's really quite simple.

The primer is formulated with a higher molecular density that causes
the end chain atoms to move their valence electrons to the next
orbital level which enhances the strength and number of chemical
bonds, thereby increasing the coefficient of static cohesion by an
order of magnitude.

Actually, I haven't the foggiest idea. When you find out, tell me why
Gojo takes grease off hands but not metal. Probably the same thing
only in reverse.


I'm a chemist, but not a paint chemist, and got a kick out of your
explanation. If you had left off the last paragraph, 99% of the group
would not have been any wiser.

Actually the op was kind of lazy and could have googled up something
like this:
