Bob,
What I've done for years is cut a piece of felt. I get it from my brothers shop, probably 1/4" thick grey felt, cut a strip 3/4" or so wide about 12" long, fold in half and push it into a piece of pvc. Inside diameter of the pvc is 5/8", the length is about 5-6". Push the felt thru til it comes out the other end. Use a round knife to shape the felt into a sharp V. Makes a great dye applicator that costs nothing and lasts for years.
