Countertop Repair

When reinstalling my countertop I accidentally used too long a screw and went through the laminate. I found some repair stuff at Lowes and also some two part repair stuff lying around made by Homax. I can't seem to find the two part stuff at any of the stores and can't find it in the Homax site. Anybody have any suggestions? It is a multi-colored laminate called Granite and has a combination of black, medium grey, off-white, and beige. A similar color would easily blend into the mix. I'm not too thrilled about the Lowes product because there is no cap for the tube to reseal it after opening it. Any suggestions?
