I know this plug issue has been beat to death (deservedly so), but since it is once again on top, I have a question that probably has been asked elsewhere------if you dont mind !

Can any of these thread sealants be used around the "nose" of the plug-----with care not to get any on the tips. I am thinking of the aluminum "slop in a can" that I use all the time for small engines, and large, with aluminum heads or on bolts that tend to clog up with rust etc. There is also a "copper" based sealant in a can, applied with a brush.
