I recently picked up a brand new Weatherby Mark V Accumark in 300 WBY that has a hand laid fiberglass stock which is painted with a camo pattern. The stock does not have knurling in the grip areas and I find it to be slippery. As this is a hunting rifle I want to correct this. What is the best way to add a texture to the stock to improve the grip? I was wondering if I could try stippling it with a soldering iron or if there is something better I could try? Any advise is appreciated.
