I am doing a classics jazz reshell. I've used classics Prowl as the base. So far he transforms almost identical to Prowl. The model's plastic I've used for jazz doesn't seem to melt with modeling glue. I'm having trouble with the doors. On the double jointed hinges I'm having troubles attaching those more than a day let alone permanently. These are the hinges that connect the door to the fenders. I cut them off prowl and shaved them down until they would fit into Jazz. I've tried modeling glue and a two part clear glue epoxy that I bought at Wal-mart. It dries superhard, but doesn't affect plastic at all. What do I need to do or use to get these hinges attached permanently? Any help would be greatly appreciated.
