I'm trying to remove the 5/16" stainless steel bolts holding down my aluminum traveler track. So far the bolt is winning the battle.
I expect the interaction between the SS bolts and aluminum while being sprayed with sea water is the cause. I have tried applying an impact wrench and hammer with no movement. Next I used a welding torch and impact wrench with hammer and the bolt has rotated maybe 45 degrees so far. I have also tried connecting the bolt and track to my 12v battery supply with jumper cables hoping it would heat and loosen the corrosion, but there appears to be too much resistance for enough current to flow. Anyone have any sure fire ideas on how to loosen this bolt?
