I get this tl 08 in February this year so like always bolts across car do not have anti seize at it. Did replace rear brake pads yesterday and managed to break one bolt at sliding pin because it wasn't anti seized. Get lucky that had one sliding pin and bolt from my old tl 03 at hand so finished job. Had problem to open bolts of wheels to because no anti seize at them either.
I'm rust fighting enthusiast and every bolt ever opened will get some sort of anti seize. Every hose will get silicon grease. Brake sliding pins will get brake grease, Permatex silicone ceramic extreme in my case. Spark plugs will get nickel anti seize. And last and actually above all underbody will get Cosmoline and Lanoline.
Here is my tread about rust fighting that has 16K views and keep going https://www.ford-trucks.com/forums/1...-compound.html .
I'm proud that I contributed to humanity.

 

Because during the day it is 90f here in mn at moment I started at 6 am. And liked it big time. I was back at home at 8,30. Will look forward to do more of early start in hot weather. Even in my carpentry job if will be ok for neighbors of that project.

 

Don't use anti seize on spark plugs!

NGK's already have a rust prevention coating on them. Just buy the correct plugs.

You're risking a bigger issue by torquing a plug to a spec that did not account for anti seize. You could break the plug off in the cylinder just by going to the specified torque.

For most other external/suspension/brake bolts...I agree that anti seize is a good idea. But watch the amount of torque you use.

Remember...lubrication reduces friction...so its easier to damage or strip the threads via torque.

 

^^^ I used nickel anti seize at my tl 2003 and my ford f250 99 without problem. Just did torque it to lower end of torque recommendation. 4.6 engine at Ford has known problem with threads for spark plugs in engine.

 

It even states it at NGK's website!!
