If you wet sanded with 2000,I would have to think you are close.
Without seeing it,I would say,try buffing the area with a paper towel first.
That may not be enough.If not,try using the paper towel to rub some wipe-on poly or True Oil into the sanded areas.Just wipe it across the sanded areas and wipe it off.You are just trying to fill the microscopic sanding scratches.Just try one spot and see how that goes.
If that doesn't completely blend it,let the finish cure for a few days and get some fine rubbing compound like FFF or FFFF from Brownells and rub out the areas,blending into the rest of the glass.Rubbing compound really helps blend areas and is easy to use.Finish by buffing with a clean paper towel.
The other option would be to lightly wet sand with 2000,all the glass and go over it with rubbing compound.
