Material Finish - A Few "bubbles" After Applying Sanding Sea

[XcitR]

I've done a material (cloth) finish on an Ibanez and have brushed on about 3 good coats of sanding sealer (Deft's). I've noticed that there are 3 small "dots" where there either wasn't good glue coverage (Titebond orig.), or the sanding sealer has raised the material - I'm not sure. I've already lightly sanded with 400 grit paper to the rest of the guitar top, but I'm not sure what to do about these small "bubbles". Should I lightly sand around them and then seal again, or should I leave it alone until Clear Coating? They're probably only "raised" 1/32 of an inch or less, and I'm afraid to sand through the material if I continue. I plan on Clear Coating with 2-part auto clear, if this makes any difference.
