What are good sources of Polymer in Alpha 20?
The primary use of Scrap Polymer is to craft AP Slugs for the shotgun. However, a box of 100 shells requires 80 polymer, which is quite a lot.
So far, the only semi-consistent source of polymer I have been able to find was computer monitors destroyed with an Impact Driver. However, this takes a long time. I ran skyscraper_01 in Departure twice in one day and was able to harvest about 600 polymer in one day.
Are there better, more consistent sources of polymer that I am not seeing?
