Is there a quick way to dissolve rubber? It doesnt have to be minutes but something I could put on and in the morning be able to remove my shackle bolts more easily? I have tried a puller, torch and banging the bolts with a rather large sledge hammer. But nothing is working. The front came out quickly but on the rear there seem to be sleeves that have rusted to the bolt and somehow stuck to the rubber and they wont come out. I need to get this done soon because I am behind schedule.
