Latex Kilz is a good primer and blocker but you probably just needed
2-3 coats to block that stuff. Similarly, if you've ever gotten trim
stain on drywall you will know that it takes several coats of primer
to hide the trim stain. (why it's always best/easiest to stain your
trim Before cutting and putting it up). This glue is probably a
similar situation and it's a dark color. Latex over oil always needs
a primer to bond the two types, oil over latex less-so but still not a
bad idea.
