LOL, you threw me on that one. So, I had to cheat.. Since you are up North you should be able to find this at any Dive Store, or on-line, depending on your preference...
Cotol-240 Cleaner & Cure Accelerator is a urethane cure accelerator and pre-cleaner to be used in conjunction with Aquaseal® or Aquasure. The solvent cleans and prepares the surface, readying it for Aquaseal® or Aquasure, speeding the tack time to 15 minutes and the full cure time to less than two hours. Cotol-240 is also ideal for removing tar, sap, glue, and other resins from various surfaces including glass, plastic and metal. Available in ½ oz. Blister Pack, 4 oz. and Quart (not shown).
