Any real differences between FK2180 and FK1000P?

You said it!.

Older paint, putting any liquid on a porus surface, it's gonna go down in.

Grumpy

Yes, of course, but what are those active and/or other ingredients that make it behave like that? With the mentioned multiple layers I experienced serious durability (Thomas did too; close to a year), but yes, the product IS sensitive to morning dew.
