Cuts easily with knife or scissors. Rustproof. No cracking.

Review: Perfect Joints! - The MF-100 Straight-Flex Mid-Flex 3 product worked just as described. It performed perfectly for my >90 degree joints. My project was a remodel of a textured ceiling. The joints were not originally finished with precision as the texture covered all the imperfections. The Straight-Flex gave me perfect joints. Two tips: 1) After the Straight-Flex is placed in the initial joint compound bed make sure to pull most of the compound out with your sheetrock knife. All you want is a thin layer underneath the product. Then let it dry overnight. 2) Make sure not to get the joint compound in the corner as you place the finish coat on the Straight-Flex. There is a blue line down the center where it bends and forms the corner. Make sure you can still see the blue line. This will give you a perfect corner joint. Definitely recommend this product.
Review: Love this! - I had less than and greater than 45degree angles to put corner bead on and this was great. Good on 90 degree corners as well. A very good timesaving product. There are good You Tube videos how to use it by Vancouver Carpenter
