Face Mask

From CosplayWiki

For when you are sanding or cutting, the dust hurts your lungs. You will need to wear a face mask. They are inexpensive to buy and can be found at many stores. They will protect you from small particles and look like small white masks that fit over your nose/mouth If you are going to be working with fiberglass or bondo you should get a mask that protects you against the fumes - these masks are much more expensive and look more like full sized gas masks.
