I'm gearing upto my SierraWest kits and I'm doing a new mix of Higgins Non waterproof india ink and 99% alcohol. The alcohol bottle is a 500ml and I added about 40 drops of the india ink. I tried dunking a piece of strip wood into the mix to check results and to my surprise no color on the stripwood.I even tried using a wire brush on the wood to open up the wood outer layer. I've never seen this before using the waterproof india ink mixed with alcohol. Am I not mixing it strong enough perhaps?
