Restoring No.3 Hales Grenade

Hi, I'm restoring a No.3 Hales and am having the darndest time gettting the brass unscrewed from the steel body. Has anybody had any luck using acetone or the like to loosen the threads? I used some white vinegar to remove the bulk of the visible corrosion, but those threads are just... stuck.
 
Whenever I've had a stuck thread on anything I've used PlusGas, which is a dismantling lubricant.
 
I don't think they have that in the US, but I will see what it's made of and try to find something similar. Thanks for the tip!
 
You might try putting it in the freezer for couple of days. The cold shrinks the brass more than the iron and they sometimes come apart easily.

I will try that tonight!

Here is a picture, btw.

Opinions on keeping the remaining paint vs. removing it? I still have a few more pieces of the brass to clean up as well.
 
Really stripping right down you could be sorry if some thing breaks

You have a really nice example there. I agree with Dave, it may be best left alone. If you try the freezing route, don't use tools - just hands and if it won't come apart - leave it.
