duct tape,

sylicone sealer,

Fiberglass or rockwool house insulation,

utility knife,

sissors,

thin foam board,

a heavy duty piece of plastic (A good shower curtain liner is the right thickness.)

a roll of the heavy duty roofing relt. (You don't need much so if you have some lying around that is cool.)

Some batting material from a sewing store

a can of rubberized raint.

a can of spray on glue.

Now you are ready. Right.

Good let us know how it turns out. LOL

Seriouswly consider how everything goes back together and where you can put insulation to deaden sound and hot/cold.
