I use a copper based grease from Carlube had the tub for years and still got half left, I use it on wheel bolts, tyre valve threads and almost anything else that may need regular disassembly or for that matter sqeaks. Such as a washer which is behind a trim on the passenger side and secures the side quarter light, no noise since.[]

Copaslip is the most common anti-seize agent used in the trade. Available on Ebay or at most motor factors. I personally wouldn't use it on road wheel threads, preferring Castrol Optimol TA which is an aluminium based paste. Regards, Clive

Another vote for Copaslip, and occasionaly silicone grease. I don't use anything on the wheel nut threads, it doesn't seem right and I thought it can have a detrimental effect on torque readings.

Another vote for Optimol TA- if you can find it! If used on wheel bolt threads I understand that it doesn't affect the torque readings as it is a specialist "anti-seize" compound not a lubricant or grease. Keep it off the surfaces where bolt and wheel meet though. A source of endless debate on the car forums![] This from the 997 owners manual, btw "Apply a thin coat of Optimoly TA (aluminum paste) on the thread and between the bolt head and movable spherical cap ring (arrows). The bearing surface of the spherical cap facing the wheel must not be greased."

I got a tin of Optimol TA from Motobins.co.uk Here

I will give the Copaslip ago....tvm

Where on the car are you planning to give it a go?

where i work(car engine dyno testing) we use a anti-seize compound called never-seez on the exhaust studs it contains nickle and it is two to three times better than copper based products (just added some info from web site please goggle never-seez if you want more info) A nickel and graphite based anti-seize compound formulated to protect up to 2400ºF against seizure and galling, galvanic and severe environmental corrosion. Never-Seez® Pure Nickel Special is a superior, high temperature anti-seize and extreme pressure lubricant. It contains flake particles of pure nickel, graphite and other additives in a special grease carrier found to enhance anti-seize performance. This product is recommended for use when applications prohibit the presence of copper, especially when resistance to corrosive acidic and caustic solutions is required. Meets Boeing BAC 5008, Ford ESE-M12A4-A, Garrett Engine Div. PCS5721, GE Aircraft A50TF198 Class A, General Motors 14001899, Pratt & Whitney PWA 36053-1 and is tested to MIL-A-907.

Exhaust Bolts....any bolts really (not wheels)..currently doing rear end spruce up.....numerous bolt seized or rusted too oblivion.....most need Dremel action to release....replacing with stainless bolts etc and need to ensure I can get these undone in future. Any advice most welcome. Regars

Can someone please shed some light on the current trend to replace exhaust nuts and bolts with stainless My limited (I know!) knowledge would say that the heat build up on an exhaust will weld stainless nuts and bolts together so they wont undo! Why dont the factory use stainless nuts, bolts, studs etc? Ok, if there isnt the huge temperatures I can understand, ie; bumper supports etc. so the stainless will be rust free and should help removal but rear boxes and cats do need to come off quite often on 993's Is it just OCD?

Stainless Steel bolts do not have the strength of mild steel so a plated mild steel is better, as said above stainless welds like to like with quite moderate heat. On the original topic, Coppaslip is very useful for general use as is any copper assembly paste, Never-Seez is good where items get very hot, I have used it on Gas Turbine Test Rigs and stripped later without problem. Dow Corning MS4 is among the best Silicone based Lubricants I have used on door seals and ignition systems for waterproofing and such it helps maintain the suppleness of rubber seals just rub it in and leave then later remove the excess, seals stay good for years with just a light smear to clean grit etc off. Ok from -50C to 200C. Note: Lambda probes are said to be effected by silicone so do not use on anything in the vicinity of the exhaust probes.

Thanks for that note about Never-Seez, I'm doing some work that that will be just right for. As for the MS4 it has now been superseded by DC4 and I'll see if it refreshes my door seals.

Spec looks about the same but MS4 is still available on ebay, of course it depends how far gone the seals are but if they've hardened through age/exposure should help make them more supple and quiet.
