Ok bighorn guys. I need your advice. I've done a search, but found nothing that helps. I'm mounting up a bighorn and noticed for the first time that there's a light line on the horns about the right level for a soaking line. I soaked the horns a bit when trying to pry them off, but I submerged them completely, so the line isn't my fault. My customer set the entire cape and head in a cooler of ice for the 2-day drive back from his hunt, so I'm guessing this is what I'm looking at -- not sure why I hadn't noticed it before. My question: what do I do to make this line disappear? Many thanks.
