About a year ago someone said to use acetone and automatic transmission fluid, mixed, to break loose rusty bolts or nuts. I've been using it and it works better than anything I've found on the market. Thank you, I've saved a lot of time on exhaust manifold bolts and nuts. Try it, you'll like it. Mix it 50/50 and squirt it on the rusted part, wait about twenty minutes and go for it. If we know that we are going to do something like this, we squirt everything down the evening before and then in the morning we just unbolt almost every one almost every time.

 

wow never heard of that

 

I have used Marvels Mystery Oil, but thanks...by the way do you have a light?
