The weather seals protect both the door and the garage. The bottom one is the quickest to wear. If there is sunlight coming under the door, it should be changed. Similarly, if there are rays of light getting through the sides and top of the door, the other seals have to be replaced as well. The vinyl weather strips work well and do not wear out quickly. Their main advantage is that they are resistant to both UV and water damage. It is best if the bottom seal is attached with the use of aluminum retainer. The retainer makes replacement easier while providing even better protection to the bottom garage door panel.
