Bumper bolt removal

[cabrioletgalaxie]

Bumper bolt update. Grabbed the two front bumper bars and went to work one last time to free the bolts. Before I began to look around for everything I need to do the electrolysis I decided to give it one more tray with a heavy hammer and some penetrating oil. I set it up the the vice and in about 10 blows and several squirts of PB Blaster the first one came out. The second one wouldn't budge so I drilled a small hole in the space where the bar is wrapped around the bolt. I ran an 1/8" hole throught the space and used lots of Blaster. Then after about 18 blows it broke free.
I was almost disappointed as I wanted to try the electrolysis. Maybe some day, but with a bead blasting cabinet it may be a while
Thanks for everyone's help. Ford Barn and its participants rock!

Sodium Bicarbonate is NaHCO3 and Sodium Carbonate is Na2CO3. So much for the Chemistry lesson. Sodium Carbonate is commonly available from swimming pool supply places. Sodium Bicarbonate is baking soda.

After reading all the posts ,i decided to try and see what would really work
mine were original and really stuck,so i figured it would be a good trial
first the electrolysis did work really good on freeing the nuts
no way would they come off with a wrench,yet after electrolysis ,they spun right off( i used the junk shock as a sacrificial anode)
then i tried soaking for several days more with the nut off
electrolysis did not free them up
so i tried the wedges.I thought that was a great idea,but alas,it did not work
so thinking that there are three places where the nut could be frozen solid ,i decided to cut the bolt in two with a cut off wheel
sure enough one bar was free ,and the other was frozen solid
even the spacer was rusted solid to the bolt
on one I was able to use a vice grip and twist the cut off end right out
but the other side was a bear,vice grips didnt work,hammering didnt work
so i went to heat,I know you have nicely chromed bars,and I really dont think you will have to go to heat,but I did
after several heat and cool cycles it still wasnt budging
so i went over to the anvil and using a hole in the top i put the head of the bolt in it and used a 3lb sledge( i couldnt take a picture of the hammer and me at the same time) and one good whack and it came right out
maybe if i used the anvil first ,i could have done it
but total time (except for the electrolysis ) was about 1/2 hr
on the electrolysis just go to any pool supply and buy a quart of PH + its only about $8 and is 100% sodium carbonate,unlike other stuff
and a quart will last you a lifetime
when done with the water,just pour on the lawn it dosnt hurt it
remember you are only using the sodium carbonate as a path for the electricity ,it is not used as a solvent
if you want, you can use sodium chloride (salt) or even rusty water,
i believe you probably could use sodium BI carbonate ,but its just not as good a conductor as sodium carbonate
