At my local Walgreen's pharmacy I can find New Skin liquid bandage in "single dose" tear-open plastic pouches. They have a generous amt. of goop in them, and easily fit in the PSP or FAK. I think just one would have been sufficient for the scratch you described.

ALSO NOTE: when lit with a match/lighter (but not a spark) this goop burns like napalm. I've used it to help ignite damp kindling.
