(probably stainless) bolt in an alu casing
As everybody else says, you're probably not going to beat PlusGas. What they're not telling you is that even that probably won't work for a stainless screw that has got well stuck in an aluminium housing, in the sense that the housing will be wrecked by the time you get the screw out regardless of which method you use.

Galvanic corrosion?

@PhilDAS and @JurekB - cheers.
I had wondered if I needed to order some helicoils at the same time.
@mdcc_tester - you might have a bright idea on this one....
I have a thread I'd like to clean/chase an M8 hole but there is an object (an exhaust) in the way so I can only get less than a 1/4 turn on it.
Is there a safe way to extend the chasing bit(?) by 10cm?
It's a 4 sided jobby:
Thanks.

Any suggestions for best penetrating fluid?
Is PlusGas still better than the WD40 penetrating stuff?
In case it maters it's for a steel (probably stainless) bolt in an alu casing.
