Why Copaslip will work for you:
Copaslip’s unique formulation ensures that it will not harden or soften and stays effective to 2000°F. It is designed to provide an insulating layer between metal surfaces so that dismantling and routine maintenance are free from breakage of fused parts. In most applications, you can put your torch away!
Copaslip is recommended by both Toyota and Nissan. Use it on spark plug threads and cylinder head bolts, behind disc brake pads to prevent squeal, for slack adjusters and pivot points and throughout the exhaust system.
