There's a Boelube thread (great drilling and cutting lube BTW)going on and it started to drift; shifting here instead.
The best penetrating oil I've ever used or tested (had colleagues in the labs at Kennedy Space Center) is Kroil (AeroKroil). It penetrates so well it will lift cheap bluing off of steel. Didn't test it on any blued surfaces of value. NOT TRYING TO START A DEBATE. For users/fans of the product, it's on sale direct from KANO Labs. Two bonus sized cans for $15 plus a flat $5 for shipping. If you're familiar with typical pricing, you'll know this is a monster deal. Hopefully someone finds this of value.
