nuck Posted July 23, 2022 Report Share Posted July 23, 2022 Hi folks. I have almost a puncture type hole in my grill from a rock. I would like to try a repair with the JB weld plastic fix but it doesn't work for polyprop. Anyone? Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted August 10, 2022 Report Share Posted August 10, 2022 If you still have the piece knocked loose, drop it in water and see if the plastic sinks or not. ABS sinks in water (specific gravity: 1.06), polypropylene floats (specific gravity: 0.946). 2 Quote Link to comment Share on other sites More sharing options...
