I'm not exactly sureabout Excaliber's issues, but my serving lasts for years on my Tenpoint. I use just regular string wax everywhere, except the center serving. In that area Tenpoint says to just wipe down the rail with their rail lube every 150 shots. I think their rail lube is just FP10. I use the tenpoint stuff or regular FP10 to wipe the rail down and all other metal parts. I don't apply this heavy at all. I apply a few drops to a paper towel and then wipe down all exposed metal including the rail. I have never seen significant serving wear on my Tenpoint. The latest string serving is starting to separate a bit, but it has not unraveled.
