I recently applied the final coat of polyurethane on a tabletop for a customer and wasn't happy with how it came out (lots of brush marks, way too thick application, I should have known better...) so I sanded the whole thing with an orbital sander (220 grit) and reapplied the poly.
All in all, I am happy with the results. It's nice and smooth, and all the brush marks are gone. However, I noticed there are one or two small areas that didn't take the poly well (see photos - larger photos in links below.)
Anyone know how to spot-fix a few imperfections like this in poly, or what might have cause this?
The wipe-on poly was applied this afternoon, so I'll have to wait a bit before making any moves. Thought I'd come here for some advice in the meantime. I really don't want to make it worse and my woodworking judgment tends be really off when I'm frustrated with a project.
Any advice is much appreciated!
