I just had some windows replaced. I have some quarter round to stain and finish. How can I match up to stain that I wish to use to get about the same color of the present wood work? I don't know the name of the color on the old woodwork. I will be staining and finishing Oak. The present wood work is Oak, and is of about a medium to light oak finish. What porduct can I use to do a one step or two step proceedure?
