re: Woodworking boys, what’s the best top coat for oak stair treads?

I think we used some type of Sherwin Williams stain and sanding sealer on mine about 10 years ago and they still look great.

My uncle is a house painter and came to help me with mine. He bought all the stuff from his Sherwin Williams dealer at whatever discount they give him so I'm not exactly sure which ones he used.

Mine are red oak.
