Okay, does anyone know where all the zinc is hiding? I've been obsessively searching all the island types and only found one. I've evn stopped my relentless usual vermillion collection and sales to find zinc. I may go mad. Someone help!

Zinc is usually sold in the State Store (for some honestly outrageous prices), but sometimes it'll go out of stock. You can find a list of materials/where to find them in my Apparel 101 guide in Player Guides :)
