Wet sanding would make all the difference! We have the same issue so I purchased wet/dry diamond sanding pads from Amazon and they made all the difference. If you look at the photo attached, the left side is without any sanding, the right side is wet sanded. You probably can’t fully are the roughness vs. smoothness here, but it really did make all the difference.

That looks great! What grit did you get down to? Grinder or orbital sander?
