Many thanks for making me aware of the product Fluna Tec. I am usually fairly sceptical of firearm related products as I have had some disappointing results in the past. Not with Fluna Tec though. I bought a new blued Tikka and immediately pulled it apart , degreased and applied the product on all exterior surfaces and on the bolt and inside the action. I was really pleased with the result , The blueing takes on a really nice lustre and feel , and the bolt is noticeably smoother and quieter in the action. I have fired well over a hundred rounds through the rifle now and the action is still quiet and smooth. Dirt and carbon cleans off with ease. I am completely sold on the product and am in the process of applying it to all my other firearms and dies.
