My driver's seat cover (vinyl) has a tear in it and I've tried patching it with duct tape.  After a
few days the duct tape seems to start curling and sliding from one edge...probably because of my
body heat and movement.  It also is enlarging the tear.  I wonder if there is a better way to patch
the seat cover, something that will last a while until I want to replace it.  I also need to figure
out a way to fill in a depression in the foam, right under the tear.  Any ideas?
