First off, thanks for the responses. I will try steel wool and paste on the backside of the Barn door and see how that looks after the poly is good and cured. I'll likely get some fine sand paper and use it with paste on the underside of the table and compare the 2 and go with the best for the sides that will show.
Secondly the different methods of finishing is endless which aids in confusion and difficulty choosing which method to use. I'll be the first to admit when I'm done sanding the finished project I am ready to move on to the next. Finishing, great finishing, takes knowledge, time, patience and a proven method. I found my problem.
If I had Sticks money I would just send it out to be finished and move on to the next project. However it looks like I will be allowing the time and choosing a method that will work for me. One that has a low amount of harmful fumes as the shop is attached to the house.
One thing that stuck with me during my recent search on finishing was a guy stating that he was just an average craftsman/carpenter but having a great looking finish made his project great.
