Shellac bubbles when drying - Finishing - Carbide 3D Community Site

I’ve had this actually happen with Roasted Red Oak and this Mahogany piece. It seems to always seal the first side nicely then When I go over the other side, the shellac has small bubbles. I think this is caused by dried wood because it also happened with polyurethane brushed on. What is the technique for preventing this? Any way to recover the piece? I’ve done this one like 4-5 times now. Scuff with a red scotch brite pad and thin layer of sealer. I’m thinking a flat razor to flatten it agai

Wood surface has lots of white bubbles/spots after applying second
