I just had a red oak handrail installed on my staircase and applied a coat of minwax stain. I suddenly realized that the two pieces that made up the railing had different grain patterns! Since that looks bad, I wanted to see if there is such thing as an opaque interior stain that I could use to get the color I want while hiding the grain on both pieces. I called a local Sherwin Williams, and I was told that the only solution would be to use an exterior stain. Does anyone know of an alternative solution? Thanks in advance.
