Penetrating fluid

[Ian2012]

Right then what do you use and how good do you think it is??

WD40 btw isn't a penetrating fluid so i am told, I have heard you can mix 50/50 pure acetone and auto trans fluid to good effect, not tried it but going to when i find 100% pure acetone, I have also read about kano oil or kroil but can't find anywhere that sells it in the uk.

I use RP-90

It's pretty awesome.

Its hard to tell I think - I generally give all nuts/bolts a blast of penetrating oil before I work on them - especially if they are under the car.
I have used plus-gas & all-in-one professional.
