I know it's sold at Home Depot, but my local one has been out of it the last 2 times I checked, so I've ordered it from Amazon. It's 2 part but comes with the two tubes connected, so there's one syringe you push and both parts come out equally. I've been squirting it out on a sheet of cardstock then mixing and applying it with a popsicle stick (Use a respirator and disposable gloves while working with epoxy). You have about 4 minutes of work time. I clamp the parts together while the epoxy cures. It tends to cure in 15 to 30 min depending on how much was applied. Then I can easily dispose of the gloves, popsicle stick, and cardstock once the epoxy on then I cured.
Also I love the test pieces. That's really good to do before jumping to large parts!
