2 part super glue?

I also love the Zap A gap plus the accelerator. As far as another accelerator try baking soda on the super glue.Baking soda is one well-known substance with this effect. If you apply a layer of superglue to a seam and gently pour baking soda over it, the glue will cure very quickly. It makes for most effective filler for smaller jobs, and the baking soda results in a slightly rough surface which is good for sanding.
