Neoprene? You can get by butchering Hard Leg Guards and Hard Arm Guards. Other than that you might try to cut down Wetsuits and similar swimming gear. Besides that, I have nothing else.
Electronic Scrapā¦ You might try disassembling some electronic components. Micro motors, processor boards, unpowered lightstrips ( etc. )
Kevlar is pretty simple. Firefighter equipment ( Turnout Jackets, Pants, Shoes ) are probably the best source of kevlar. Kill Firefighter zombies on sight and wash the clothes, you might get something nice as a bonus like a gas mask. Police Zombies are also an option, but they drop kevlar vests rather ralely. Also combat boots, they can be sometimes dropped by other zombies, but the best bet is to hunt down Military Zombies.
