Is never seize (sp?) recommended on spark plugs for aluminum block outboard motors?

The automotive folks recommend it for aluminum block auto motors. I have never used it but it sounds like a good idea? Thoughts?

Thanks

Ive been told not to use it on 2-stroke outboards. Just tighten the plugs to spec they should be fine. Please correct me if im worng.

I see no reason not to use it and many reasons to use it. It is low cost insurance against a plug seizing in the head.

Two-cycle outboards usually keep oil on the plug threads, during operation. This eliminates the need for anti-seize.
