Sealant bonding question

[Nate3420]

It may be a dumb question but I've been curious. How do you know if you are having a sealant bonding problem? Just that it wears down quick or do you see a problem when applying and buffing?

If you prep the surface and its squeaky clean. There should be no issues bonding.

And keep it dry for 8+ hours.

Sounds good. But I've often wondered about layering. It may be clean, but it sure isn't squeaky.

The former. The root cause would be something related to how the paint was prep'd.
