i replaced my slave clutch cylindera few months back... and i didnt replace the master coz the clutch line that went into the master cylinder wouldnt budge! i tried an open end, channel locks and vise grips. NOTHING! it began to round off so i decided to stop.

ok so i go to autozone today to pickup a flare wrench for the clutch line and i picked up some PB BLASTER. i sprayed the fitting and let it soak in and ate dinner. i come back out to give it a whirl, NO GO! it started to round off again! ack? what to do?

i guess i could cut off the fitting and get a new one and a flare tool and redo it?

any suggestions?
