The plastic fresh water tank in my 1966 Overlander has sprung a leak. Since I'm on the road in Mass, heading to the OBX rally next week I don't have time to order a new one. Would a JB Weld product work to fix the leak?? Has anyone fixed a tank before and with what? On the road, need a quick fix. Paul Waddell WBCCI/VAC/WDCU 1270
