Seized Guide pins - was... "pads/disks for 90"

Speaking of which ... 
Is antiseize paste sometimes used as guide pin lube?
It would seem like it might be perfect.

I just did brake work on front of the 89 200q.  One of the guide pins was
totally seized ... the carrier is now junk.  I beat on the guide pin with a
three pound hammer and it didn't budge.  Paid just under $50 for a new G-60
carrier.

Other brake caliper replacement observation...
Last year I replaced rear calipers with rebuilt and was surprised to find
they were bare metal ... no cad plating or other finish.  Now they are
rusting badly and I wonder about their long term survival, esp. the parking
brake mechanism.  I could (should) have painted them but I don't know how
effective that would be in the area of the E-brake mechanism.
