Window felt (top of picture) Outlaw uses on all bodies with power windows.  On the Willys we install the felt on both sides of the door (2 - 6' pieces cut in 1/2) it just gives the door a very clean look

Use 3M weather stripping (black) to install felts

Use resin to install window channel - some guys also use Bratts nails

Both the felt and channel have a stainless bead on the edges
