Get this:  epoxy that you don't have to mix!  This is amazing stuff, and a special nozzle on the cartridge mixes the two parts better than you could ever manage in a mixing cup.  This is the perfect blend for CLC LapStitch™ seams.  Here's the official griff from West System on the product:

Six10™ Thickened Epoxy Adhesive combines the strength and reliability of a two-part WEST SYSTEM® Brand Epoxy with point-and-shoot convenience. The self-metering coaxial cartridge dispenses a gap-filling structural epoxy that bonds tenaciously to wood, metals, fiberglass and concrete. The tube comes with a static mixer that lets you lay down a bead of thickened epoxy with any standard caulking gun.

Six10's shear thinning properties make it "thinner" as it's worked. It can be easily tooled into a non-sagging fillet or used to wet out light to moderate reinforcing fabrics like fiberglass. The hardener provides a long open time but has fast thru-cure. Six10 stays workable in the static mixer for 42 minutes, making it practical for long or complicated assemblies.

Each tube of Six10 comes equipped with a static mixing wand. We also have replacment Static Mixers.
