I did a clear pour about 1 1/2” deep, then next day while the epoxy was still soft I added some pebbles. As they sank of course they left micro bubbles and I couldn’t figure out how remove them as they didn’t make it to the top. The epoxy is now cured with the bubbles still there, can I take a router and remove the bad spots then sand and repour into the holes? Without seeing seams. I would need to remove a channel 1” wide 6” long and 1” deep.
