No faith so convert me.
omega 24 v6 - 30/1/10 at 05:23 PM

I'm going to have to do some work on no2 daughters car soon. I'll need to change the brake compensator valve on her 206. you know how it goes folks seized brake nuts and bleed nipples lead to replacement pipes and then cylinders etc etc untill you get to a point where the fittings can be seperated.
So as I've never had any faith in penetrating fluids/oils can any of you guys recommend me some so I can apply it now and leave it for a week or so.
Thanks in advance folks.

Everyone seems to love this stuff, i'll have to get myself some sometime, Is it good for spraying bolts to stop them getting rusty? I'm thinking in particular the exhaust clamp allen bolts.

i'll third its good stuff - years ago i got mine from halfords. Its not cheap there but on a Sunday i had no choice and didn't regret it.

Certainly is good stuff, when i first used it it came in retangular tins with an ally spout that fitted into the top, mind you that was in the 60s.

hi, when i get a really stuborn brake line fitting i spray with wd40 then use a pair of mole grips tightened up real tight on the union and very carefully turn a little back and forth till free if your really carefull 9 times out of ten you can get them undone and reuse the union
theres always going to be the odd one that wont shift
do this before youve ruined it by slipping with the proper tool

I try to move the rusted bolt even just a little to crack the rust seal.
Then spray with Plusgas, and leave for a day with a small top up spray. (Depends on how much time you have) This usually works on the worst of rusted bolts. DONT rush it!

As for stopping bolts rusting in their threads, Coppergrease is second to none.
Used it on just about everything on the Land Rover.
Tried an tested. Just a thin smear needed.
I have had bolts come undone after 10 years of hard life on the Landy, cost the were lubed with coppergrease / copperease.
Just be careful on certain bolts that are Mission critical like suspension and brake calipers etc.

But works well on exhausts etc.

Plus gas or diesel, or plus gas then diesel brushed on after. An old truck fitter I used to work with swore by it.

I'll second that. We used to soak old steam valves (and they don't come any more rusted than that) in diesel for a couple of days before even trying to get them apart. Worked a treat.

I used to use copper grease on everything as above, but then i read somewhere (i forget where, but maybe an engineering manual or college notes) that the reason copper grease is used on the back of brake pads, is that it attracts the corrosion away from the brake components??
Ive never had any problems with using it in the past, but that did concern me somewhat so i now use Moly high temperature grease, and copper slip where i need it.

Anyone else confirm this? - or am i talking bollocks!?!?
