Do you find AeroKroil equal to or better than 50/50 mix of ATF and Acetone? Just started the 50/50 soaks today. Thanks for reminder that I have not utilized my long punch that might allow mr to more than tap on the bolts. Unfortunate aspect is that any penetrate needs to wick upwards rather than soaking downward.
Please no comments to Remove Front Clip or Remove Inner Fender (another GTO group I am member of). These actions are no benefit unless I have to cut the headers up to be able to use a box wrench or socket as the Frame is the main obstruction.
I have used both PB Blaster and Kroil.
I have found Kroil to be the better of the two, it even works on rusted muffler clamps.
Kroil also wicks up.
I have a sawed off metal cutter I put in my air chisel I call "The Blunt Instrument" I use to hammer frozen bolts with.
You can also heat them with MAPP gas and squirt them with Kroil and it will be drawn in as it cools.
One of the worst I dealt with was a water pump stud on a Jeep.
I hammered, heated and soaked it for over a week in the morning and evening before I was able to run it out using double nuts on it.
Try not to round the head and use a line wrench if you can get one on it.
Line wrench crows foot might get in there.
Grinding the side of a box wrench might even work to get a better purchase on it just to break it loose.
