truing

EDIT: having taken a few out to see how inners fit as outers I realize it doesn't even want to line up. I'll leave the original post as it was. end edit. I've just laced up my 18" rear wheel using stainless spokes, the pattern is good, none of the spokes are bending or interfering with each...

I'm about ready to lace up my first set of wheels. Searching on here I've found some great resources on how to do it. Some people are recommending using a thread lubricant on the spokes. This makes sense but what do you use for a lubricant, grease, oil...or does it matter? Thanks Bill
