Not sure how well a blow torch work on car bolts near lights as there's typically some bodywork nearbyWD40 can help. But sometimes they can be past the point at which penetrating oil is of much benefit. Heat is the best option. A blow torch or oxy acetylene ideally.
This guy and AvE are great for all sorts of info and they both refuse affiliate links to keep content unbiased. AvE is not family friendly language and is why I won’t link his penetrating fluid vids .
Heat is the best way in the end
Not sure how well a blow torch work on car bolts near lights as there's typically some bodywork nearby(although I know under the gear blowtorch use is common).
They are sore about Trump not being indicted. They'll get over it.
If the bolt is sized in a bush your not getting it out with penetrating oil. There’s nowere for the oil to penatrate. Heat and a a few ***** with a hammer might work but you’ve destroyed the bush with heat. Cut the bolt and replace bushed part and bolt.As per the OPs other thread he's trying to remove the axle bolt. A penetrating oil may work if you've got time to keep spraying it on and letting it soak. As I said in the other thread we had to use heat on the bolt in order to get it to budge.
- the effect of the vapour, from his research .. there some fairly high fraction petroleates in the plus-gas, anyway. ... homebrew versions apparently use acetone.WTF sort of random response is that
Oops I misread it as penetrating fluid to get out bolts in a bulb (in my defence the next thread down at the time was headlight bulbsAs per the OPs other thread he's trying to remove the axle bolt.

Anyway, I might try out some of the other suggestions as I have 4 nuts I'm trying to undo on the inside of the door to my inset multi-fuel burner, to be able to replace the glass, and as you can imagine they are rusted on tight. Have sprayed them with WD40 for 5 days before attempting and they will not budge.
Am worried about shearing the bolt, as they are studs that are part of the door frame.
Correct! I really don't care about him. Just bemused he's still alive tbh!
As for your bolt issue - WD-40 is at the weaker end of penetrants, it's really designed as a water displacer (hence the WD bit). There are better types on the market. 5 days is plenty of time for it to work if it's going to work.
I'm confused by your description - you've got nuts that you're trying to undo, but you're worried about shearing the bolt as they are studs?
Got a pic?
Without looking the I'd suggest heat would be your next port of call.
Where did I say anything about shearing and studs?
Is it just heating up bolth the male and female part cracks off the rust and allows some movement?
