Dr. Mike's Formula 2 Model-n' Crafter's CA Glue uses 'molecular integration' to form bonds between acetal* resin parts that are stronger than possible with other adhesives. The gap-filling, shock-resistant, low-odor formulation has an extended shelf life (up to one year after opening!) and also works well with traditional materials: plastic, resin, metal and wood. One small drop is all that's required for superior performance. Reaches maximum strength in 24 hours, or within seconds when used with accelerator. 1/2 fluid ounce in applicator bottle.
