Fiberglass in Fallout 76 is one of those items that seems to be rather easy to acquire and goes into seemingly EVERYTHING you craft. It can be used to craft various different armor pieces, weapons (and weapon mods), Power armor (and power armor mods), as well as random explosives, workshop structures for your CAMP, and more.
Fiberglass is found in a number of different ways, in the more casually found items, so make sure you grab these when you see them:
Abraxo Cleaner (and Industrial Grade)
Aluminum Canisters
Cigar Box
Composite Ski
Industrial Cleaner
Jangles the Moon Monkey
Rat Poison
Telephones
As you can see, you’ve probably come across these type of items on the daily, and know where a couple are. For those of you unsure as to where to get a LOT of these items to quickly farm a lot of Fiberglass in Fallout 76, here are a couple locations to help you get on that grind:
East of Tygart Water Treatment
Flatbed truck on the road with tons of Composite Ski’s
