I never saw glue on a core before. It may have been a random drip from a bottle of glue where he stored it or maybe original buyer didn't like the bent fins.
Some bent fins are normal from handling. My first intercooler from WBS years ago was shipped loose in a box with all the other parts. There was some packing paper and a lot of bent fins.
I can live with minor bent fins but the giant pen like stabbing in the first picture on the bottom?
