Will PB Blaster free a stainless steel bolt frozen in an aluminum
casting? Will anything loosen such a bolt in such a casting? Serious
question. My bow fitting is aluminum secured to the boat with a stainless
steel chainplate. But the bolt that holds the forestay in place is
stainless steel inserted through ears on the casting. And it's frozen.


Can't comment on PB Blaster but have had pretty good luck with Kroil
from Kano Labs for many applications.

I'd call one of them and talk to the tech service people.
