Perfect for expansion joints
I purchased a home that had never had flexible sealant in the expansion joints. This was perfect to push into the joints before applying sealant. The quality is great and the sealant adhered to it with no problems.

It's good
Used this for a hood that was floppy and it looked great. Can't say how good it is for the intended purpose. It's flexible just the right size and stiff enough to make my hood the right shape

Works, but costs to much for what it is.
Works well and is flexible, but expensive for what it is.

Awesome
Amazon wouldn’t post my original positive review due to having the word “crack” in it. This fills cracks awesome. Amazon, do better.
