Penetrating oil recommendations

[budd]

I’m about to start the restoration of a 1967 Sunbeam Alpine sports car, so I think I’m likely to need some penetrating oil to loosen the inevitable seized nuts and bolts, but before I buy the default 5ltrs of WD40 I’m wondering if there’s anything else that’s better? WD40 has traditionally been the most popular pen oil but is there anything else I should consider? because I think I’ll need all the help I can get with a car that is the best part of 50yrs old .BTW I'm more interested in bulk products ie 5ltrs rather than aerosols

Other than that heat is your friend.

A +1 on plus gas. Expensive, but it works!
No idea if it's available in the sort of quantities you're after though.

I use something called (Action can) AC-90 I was given a few cans and it seems much better than WD40. they do other penetrating oils too

Equal parts automatic transmission fluid, brake fluid and Marvel Mystery Oil. My neighbor has a thing for old tractors. They are rust buckets when he starts to tear them down. He hits them with this mix a few days before he starts work and never has a stuck bolt and that is pure amazing.

similar thing 50-50 ATF mixed with acetone, I think the acetone carrys the ATF into the threads so I suppose other solvents should be just as effective, diesel, etc

Plus Gas is amazing and lasts yonks as you don't use much for each application.
