Do you apply these under, over or both?

I think applying both is overkill and create “too much” a filter situation. One os plenty and usually on the outside. But i do not know your intended use. But again one is plenty and on the outside

Will they cover 2 in hole?

Our stickers are only 2cm and can't cover 2 inches.

what is the material?

No idea. But its breathable. Seems like a poly.
