After my last coat of epoxy, it was a few weeks until I got back to it so I sanded the sruface to remove any blush. Then....more stuff got in the way and I was unable to apply the next coat of epoxy. It's been a few months. Will the blush return after sanded? Do I need to sand again? This has happened a couple times and I'm concerned that in a few areas I'm getting close to the weave if I sand anymore.
