I went to the local Home Depot today and found the garage door gasket. It is actually smooth on the outside and foam on the inside,is very flexible, and weighs almost nothing.It has a flat surface(1") which can be attached to the bottom of the front bumper cover with
3M double sided tape. A roll of the gasket is ~$10. The tape is~$5. I'm most likely going to put it on in the spring. BTW sj, they also have the style that is on your door if you ever need to replace it.
