I need to replace my T-style (two channel) garage door seal. My garage floor is uneven and water seeps in on one side.
Old seal is "U" type. I've seen a "U+O" type, with an O inside attached to the bottom of the U form. One manufacturer claims it's more heavy duty against weather and creates better seal with extra cushion. However, amazon had some reviewers saying the U+O type kept falling out of the channel and off the door.
Does U=O really keep water out better than just a U type?
Is the added weight of the "O" a fatal flaw?
