Recommended for use in spots where sealant isn’t visible.

When you have a job where the color of your adhesive/sealant doesn’t matter, consider using NovaFlex Twilight Sealant. Same great quality, but at a fraction of the price.

NovaFlexTwilight is created when our production line switches from one color to the next. During that transition period, the sealant meets our stringent performance and quality standards, but doesn’t match our color guidelines.
