I'll see if that's the same JB as I tried using to fix some parts on the wagoneer. It worked OK, but have had better luck with two part permatex plastic glue. Got pics somewheres. Cant find right now. :rolleyes:
For the grill and some other parts that turned out to be ABS, acetone worked, especially with little scraps of plastic mixed in. ABS pipe cement worked really well on the grill.
