CoreGuard is the solution.
Water, dirt and centrifugal force work together to wear out the aluminum channel causing your brushes to pull away from the core. Once this happens your only option is to replace the entire core which is an expensive and time consuming investment. CoreGuard creates a barrier that protects the core from erosion.
How it Works
CoreGuard slides into the C-Channel between the core and brush attachment, creating a barrier between the core and dirt that will erode the aluminum surface.
