Trying to get the 2 part caliper off my 95 Grand Marquie. I tried liquid wrench on these 3/4" bolts, and am about to use a torch. My question is: since "liquid wrench" is flammable as hell, how long should I wait before taking a torch to those bolts? Its been awhile since i've used one and I dont want to set things on fire without knowing any precautions.
Thanks
