I used it to fill the empty void in the garage door gasket.
I used the backer rod to fill the empty void in the garage door gasket. I'm not sure why manufacturers use these lame gaskets that flatten out immediately? I replace the backer rod every few years.
Not much to say. Product is what it says it is. No defects. Shipped out quick. I'm using it for a cosplay build, but I'm sure it's just as good when used for its intended purpose.

Had a lot of pretty big gaps around the kitchen floor after we removed all the cabinets and there was definitely a draft. I bought all four sizes and the cabinet installer, when he saw it, said he uses the stuff all the time and it works great. That's good enough for me.
