Where to buy Optimoly TA Paste?
Discussion
Just bought some brand spanking new wheel bolts as my old ones were all discoloured and rusty.
Manual states that I should apply a thin coat of Optimoly TA (Aluminium Paste) to the threads before fitting.
Anyone know where to but this stuff? I`ve only come up with mulitple packs 5 x 1Kg for £140+ so far.
Any suggestions
?

?Laughable.
Get a tube of copper ghrease, as used on F1 Cars for £4
Cheers

Agree with Stuttgart...never used anything else on any of my cars...a single tub of copper grease has lasted me about a decade so far, and still loads left!
Thanks guys, sounds like you two have the most cost effective solution...Cheers
I got a tube from OPC as per part number quoted above. Naturally it's available from a BMW motorbike parts place for less than half the price!

Don't use copper-based paste on the wheel nuts. When it gets wet the steel/copper/aluminium combo does something I dimly remember from chemistry lessons, with resultant corrosion. If you look at the workshop manuals, Porsche are very particular about when to use the copper-based Optimoly HT, as opposed to aluminium paste Optimoly TA. As ou rightly say the TA is recommended for wheel nuts.

Quite right. Amazing how many people are ready to chime in with poor advice. http://www.motobins.co.uk/displayfinal.php?functio...

When are you going to see past the Porsche myth.
£18 per tube ?
Wax for £1700
As for chemistry, I think you're over thinking the situation.
[sarc]I believe you can get screenwash fro Porsche for £14.99 for 5 litres.
Don't use ordinary water on your 911, use de-ionised.
"Water reacts with iron to form iron oxide, so you must use special screenwash"
"Ooh ooh it does"
"You must use the special stuff, its in the manual, so it must be used"
[/sarc]
I've yet to see any wheelnuts fizzing.

Well, in over 20yrs of meddling with all things car related, I've never seen/heard of/experienced wheel nuts or bolts seizing in place because copper grease had been used. Yes, I am aware of what bi-metallic corrosion is, thank-you...

That's correct Darren - the TA is only recommended for alloy nuts.
...and David has a 996 Mk2 GT3, which has steel wheel bolts, not ally nuts...Actually there is a potentially very good reason for not using copper grease on certain threads, and that is because of the significantly reduced coefficient of friction with the grease applied, it is possible to exert up to twice the actual force to the bolt/nut when applying the same torque as opposed to a dry thread. So, the threads can be over stretched when using this product unless you know what you re doing. I'm not sure if Aluminium grease has the same effect, but I suspect not, and that is probably why this product is preferred.

I bought a 100g tin from Motobins, as the 20g tube I bought from Porsche over 5 years ago was beginning to run out!

The Porsche workshop manual states that copper paste (HT) has no effect on tightening torques, whereas the aluminium TA has a "slight effect".
If the workshop manual specifies TA for wheel nuts then that's what I will use. It's not a grand money making scheme for Porsche (how many Porsche owners do all the work on their car?), and I would rather not deal with a snapped wheel nut. They are conscientious engineers and throughout the manuals they take care to specify HT or TA paste so not self-interest. This is very different from flogging people Porsche screenwash etc. If they specify HT (big steel bolts) then I will dip into big pot of generic copper grease.
Corrosion effects are real from combos of copper, aluminium and moisture. Porsche specifies copper paste on threads of bolts going through aluminium suspension parts, but warn about not getting any on the bolt shank where it would be in contact with aluminium parts.
Working on old Porsches - any old cars - would be generally easier if previous owners/mechanics were more conscientious in using the appropriate anti-seize on fixings.

I have an old tin of copper grease and a tin of Optimoly HT. They were both inexpensive at under a tenner each and will, such is their infrequency of use, likely "see me out".
I'm certainly not keen on buying Porsche-branded lubricants but use what is recommended / appropriate, reasoning that those making the recommendations know more than I do as I'm not a mechanical/materials engineer.
Happy reply-to-five-year-old-threads day!?

Wurth, Halfords, whatever.
Porsche don't brand the pastes - Optimoly TA has been made for years by Castrol. If you buy at OPC you'll get a Castrol tube, with Porsche part number sticker on it.
The important thing is the type if grease. When the manual calls for Optimoly HT use copper anti-seize, when it specifies TA use Aluminium anti-seize (hard stuff to find, so may be easier to buy from Porsche).
