Spark Plug Anti-Seize
Hello ,
I'm new to the HD. Purchased my first HD 3 weeks ago. 2007 Ultra Classic. I have been doing a bit of reading. The service manual calls for using a Loctite Anti-Seize when changing the spark plugs. Think they are refering to the Stick # 37616 Copper. Any thoughts on this ? And what do you use ?
Thanks !
Clem

Any anti seize will do. I sue the silver anti seize on spark plugs.

Anytime you have two dissimilar metals attaching to one another you open the door to corrosion. Now I've never noticed a good chrome ever do that, but usually even with those types of parts the threads are not coated as well and thats the point of contact to worry about. Might as well get at least a large container of silver Anti-Seize for general applications. For electrical connections like battery terminals I use the copper type. Stops corrosion, but if overused can be very messy. For small electrical connections I use dielectric grease. Either application helps keep water and moisture out, and with today's electronics, thats a big plus.
With either product remember, a little goes a lonngg way.

I use the silver....I never used anything before but a slight coat of oil but I noticed some serious resistance when I yanked the plugs last time and I was praying I didnt have a problem getting it out. Since then I used the silver.
So whats the differance between the copper and the silver besides the obvious?

I have always just coated the plug threads with oil, and never had a problem. I use grease on the wheel axles also, instead of anti seize. Never had a problem with those either. That was standard procedure in my old 84 Sporty manual, but I realize we are talking about steel to alloy on the later engines, as far as spark plugs go. If I ever have a problem with just oil on the threads, I will probably change to anti seize.

I am an old drop-of-oil-on-the-plug-threads guy too. Never have had one seize. I am not opposed to the anti-seize either and if I could ever think about it while I am in the parts house...I'd probably purchase some, but so far the oil has worked for me.
