A while back there was a thread on using a homemade concoction in place of WD-40, Kroil, or Break-Free to free up rusty and seized bolts... I'd like to take this opportunity to relate a personal experience in how well this "concoction" can work.
Recently the passenger side exhaust gasket (donut) in my truck finally failed. Taking into consideration that it likely hadn't been replaced since '78, it was probably due. At any rate, I wasn't all that keen on having my ride sound like a logging truck, so I set about trying to replace the gasket.
The studs in the exhaust manifold were rusted till they didn't really look like they had threads anymore, but I didn't have the bucks to take it to an exhaust place, so it was do it myself or nothing... I soaked the whole mess in WD-40 and waited a couple of days. Nothing. Not a single squesk as I tried to turn them loose.
That's when I remembered the "concoction" I'd read about here... I did a little Googling and found that the most accepted formula for this stuff is a 50/50 mix of acetone, and automatic transmission fluid. I mixed a batch of it up, and put it in a small sprayer I had.
Long story short, after soaking the the fixture in the mixture (hey that rhymed), I was able to remove the nuts, re-tap the studs, and repair the assembly.
Big thumbs up to the acetone/ATF mix! It works!
BTW - the attachment is a pic of one of what was left of one the nuts I removed using this mixture.

Hope nobody notices this one.
