How do you replace a threshold seal on a garage door?

Our garage door bottom threshold seal from North Shore Commercial Door includes installation supplies for affixing directly to your garage floor beneath your garage door. After removing any old threshold seal (Use acetone or grease- and dirt-dissolving cleaner), use a pencil or piece of chalk to mark the length from one end of the door bottom to the other. Then, mark each end of the bottom width of your retainer. Apply three rows of adhesive and very carefully press into place. Allow 24 hours for the adhesive to dry before driving your car over the new threshold seal on your garage's concrete floor.
