This might seem strange, but I am looking for the mother of all glue to bond two pieces of plastic together. What is the strongest plastic glue available? Any suggestions?

Depends on the type of plastic; if it is thin or lightweight plastic then the modeling cement creats and excellent bond. For heavier plastic a two part epoxy will more than likely bond stronger than the components.

They make a 5 min. 2 part epoxy that would seal the gates of hell.
Sounds good.

But even with lighter plastic, the two part epoxy would still work well wouldn't it?

Yes it would, and like tigs40cal said, it will set quickly and when I used it the plastic broke before the bond did.

While not specifically for plastic, I use a product called J.B.Weld for most anything I need to bond. It is a two part epoxy type material, comes in two tubes (red lettering on one and black on the other). Mix equal parts well and apply to whatever you want to bond. sets up in about five minutes and cures in about 24 hours to a grey color You can sand and shape it to match the contours of the repaired part. Almost like Bondo - I've also used it for small patches in rusted out sheet metal.



Available at Home Depot or Lowes.

Believe it or not, good old super glue is pretty darn good on most plastics. I personally use AccraBond's S-2500 Ethyl Cyanoacrylate. It's available in 3gram-1gal containers. The 2500 is a thicker liquid but not quite a gel.
