Thanks for the reply. So I do what you say and then put on another coat of URETHANE and the scratches will go away? I was a couple drinks deep when I wrote last night. To be clear I had already painted, sanded, painted, put on the first coat of urethane, and then started to sand with 220 when this happened. The box actually had looked pretty good before I sanded the urethane coat, but was trying to get it perfect and just following all the instructions I had read. I wasn't expecting the urethane to scratch up so much when sanding, but I'm a complete novice at finish painting.
