McNett's Cotol-240 Cleaner / Cure Accelerator is a curing accelerant and pre-cleaner intended for use with Aquaseal urethane adhesive. With its mild solvent-based foruma that cleans and prepares the surface, readying it for glue, Cotol-240 speeds Aquaseal's tack time to 15 minutes and the full cure time to less than two hours. Great for removing tar, sap, glue, and other resins from various breathable fabric surfaces, we offer Cotol-240 in convenient 1/2 oz bottles, with handy applicator brush included.
