: Got the glass done and three fill coats on the deck. After the first fill, I

: Nope!! I think they are here to stay, unless I sand the graphic off and

I think the first fill coat was applied too soon over the cloth, and/or possibly the wood under the graphic area was epoxy starved. "Scraping the bumps" with additional epoxy and pressure from the applicator may possibly have worked tiny air bubbles or even a void into the cloth above the butterfly.
