Please help:
I am a beginner woodworker. I'm re-finishing a table, and am working the final sanding of my polyurethane layer. I've never finished anything before, so I of course gave myself the Google U. educational course. I have 5 layers of Minwax Wipe-on oil based poly (satin finish) on the table, having sanded with 220 lightly (in the direction of the grain) between each application.
After the last coat, I let the table dry for 2 days, and went out this evening to try the final sanding/finish. I thought I'd try a wet sanding technique. Googled that too and followed what I saw/read about how to do it. I started with a 320 waterproof sand pad. Lubricated with olive oil (I didn't have mineral oil). At first I thought it looked real nice, but when I wiped all the oil off, I noticed the scuff marks were very visible when not looking at the table straight on (see pic below)
Unlike every other sanding, I used a circular motion this time. My question is, "how do I fix this?" Things I'm wondering:

- Is this normal for 320 grit?
- Will the scuff marks dissapear as I transition to a higher grit paper?
- Should I be using a circular motion?
- Mostly… did I just ruin my finish?
