I built a glider rocker for the porch. It's made with oak and I want to
paint it. I think I should use something to fill in the grain to make the

First, it's your project so do what you want.
At the same time, why would you want to paint it? Did it come out
poorly?
But, if you do decide to paint it, I would use MinWax Wood Filler and
then use a shellac primer.
