Re-Installing The Dust
When I put the dust
cover back on the door, I first align the
plastic sheet with the glue marks that are still
on the metal door shell.
I apply a couple pieces
of masking tape at the top of the dust cover to
hold it in position. Then I just replace the
door panel. Over time the dust cover will again
stick to the metal, especially after warm
weather softens the glue.
I don't normally glue
the dust cover because there is too much chance
of getting glue on the interior of the car.
If I HAD TO glue
the dust cover back in place, I would probably
use automotive weatherstrip adhesive or a spray
can of trim adhesive, because these products
stay flexible after they dry.
