I'm not disputing what Muck says, I'm just questioning why it is that, given that 'Copper Slip' is a grease of sorts and therefore a lubricant that just happens to have copper in it, copper would be marked down as the metallic element in sintered pads that causes the high wear of discs and is therefore the most abrasive. -- JackH 98 Honda VFR800FiW 03 VW Passat TDI Sport (resting) 89 Vauxhall Nova 1.3 Pearl (for sale) 00 Peugeot 306 HDI Meridian

The reason it works as an anti-seize compound is because it puts a layer of what's known as a 'dissimilar material' into the joint and copper is just one small part of that compound. Easy to understand.
http://www.molyslip.com/Products/Copaslip.html Ok... not disputing what you say but the Molyslip site states the following: a.. At points of high friction: Copaslip protects where conventional lubricants break down such as drawing and forming metals; lathe centres and slides; wire ropes and chains, (particularly In very arduous conditions). a.. In any assembly process: Copaslip reduces nut driving torque requirements compared to oil or grease In addition to greatly increasing the ease of dismantling. Use as a lubricant behind disc brake pads to reduce squeal, on pivot points and adjusters; on manifold, muffler and pipe bolts and connections; spark plug threads and cylinder head bolts. Hence why I was under the impression it's a lubricant / grease of sorts. Oh, aye. I still don't quite get why, given it's soft compared to iron etc, copper would be the most abrasive metallic element in the compound that makes up a sintered pad though. -- JackH 98 Honda VFR800FiW 03 VW Passat TDI Sport (resting) 89 Vauxhall Nova 1.3 Pearl (for sale) 00 Peugeot 306 HDI Meridian
