Best penetrating fluid?

Recommended Posts

What is the favourite of the hands-on folks here?

 

WD40 is of not much use when it comes to rusted/seized stuff.

 

PB Blaster is the one Americans go for, but it is not sold in Europe, it's probably toxic as hell.

 

PlusGas is sold here on some motor factors, not sure how much better it is compared to WD40.

 

Anybody know of another product that actually works?

 

Thanks guys

I changed the rear hatch rubbers the other day, and some moron had attempted the same before but fecked the screwhead and left it like that. Thank God he hadn't tried to do the other ones.

Anyway, with the screw head damaged, I couldn't get it out. I tried blowtorch, hacksaw and long screwdriver, impact screwdriver, nothing.

then I decided to nuke it -- big hammer and chisel: did the trick, the bastid broke free, but boy did the whole car get a hammering. There was LOTS of dust that got loose from under the wing, that was supposed to be clean!

 

If I had to drill this one out I'd be kinda stuck, because there is no straight access to the back to do it square.

 

Don't know why, but this made me think that I need a proper penetrating fluid in case I need to dismantle something in the suspension.

Don't get me started on calipers now.

I had to fit the calipers back because the pins would not get free, not for love nor money. I was banging so hard I risked breaking the calipers, they mushroomed but wouldn't move the bastids, no more than 2-3mm. I've got to take the calipers off and press them out, there's no other way I can see.

I'd definately try this liquid wrench thing, WD40 is totally hopeless in these cases....

The screws on the hatch rubber are held in by some sort of proprietry JDM loctite type stuff

 

am in the process of trying to get them un done. have killed the screw heads so have decided to use, easy out drill bits. Had to buy a drill and wait for it to charge... not its bloody raining so i cant do it till tommorrow.

easy-out drill bits, what a joke...

 

I haven't had luck with these I'm afraid. Let's hope you'll be more lucky.

Even when drilling a pilot-hole with an extremely hard drillbit, the 'easy-out' crap wouldn't grab properly. In fact they got blunt. Both of them.

 

If there is some head protruding, nothing beats chisel&hammer, (don't laugh)

You turn the fecked up screwhead by hitting it on the outer radius using a chisel to cut in the metal.

Harsh, but if you get the angles right and the hammer is big enough and used sensibly, it will get it loose. The screw will be unusable now obviously, but this is the step before utter desperation (drill head off etc)

 

A good penetrating fluid won't hurt. OK these ones have lots of loctite blue from the factory, and they used Phillips screwheads (idiotic choice)
