Does anyone know where I can find some information about the chemistry of waxes/sealants? I assume a wax will bind to paint through a hydrophobic interaction, but I can't find information about sealants. People mention "cross-linking" but the cross-linking is what to what? And I think of cross-linking as a covalent interaction which seems unlikely. Why I ask: There is a new company rep on the Meg's forum who seems to be okay with "topping" almost anything with almost anything else (I'm exaggerating...a little) while the old rep would say upfront that sometimes the second coat wouldn't stick etc... Just would like to be able to figure it out myself.
