The nice thing about those AMK repro nuts are you can remove the black disc sealer and apply to an original re-plated nut.  It will squeeze out when tightened like in Jeff's pics.

Might even work better if you applied a coat of wax (paraffin or car) to the back side of the washer so the sealant would slide and spread with ease

No need, it squishes out just like original.
