This feature was appealing, especially for projects where excess weight could be an issue. Plus, the fact that it’s resistant to water and chemicals made it a no-brainer for various applications in and around my home.
Key Features That Impressed Me

- Apply and Clamp: After mixing, I applied the epoxy to one surface and pressed the parts together, using clamps or weights to hold them in place while it cured.

Potential Drawbacks I Noticed
While I’m a fan of Carbonlite, I did encounter a couple of drawbacks:
