I couldnt find a thread on this so i thought it would be a good topic. I dont no how many of you use thread lock on critical parts like engine mounts but i always have. A bottle of the stuff will go a long long way, but its expensive. Anyone heard r no of a jack leg method or any substance that servs this purpose well, but also something that you can loosen when the time comes. Heres a list of my methods iv used be for...... commercial thread lock, super glue/CA but can be tough to loosen), using pliers to ruffen up the threads on a bolt below the nut so it wont back off. Any other proven methods?
