How to Fix a @#%!! Bisquit Error

Not much explanation here, just a bone-headed goof up, and then pig-headed insistence that "it won't look that bad." Had a nice piece of quartersawn beech that I used to face a weight-relieved pine body and make a matching neck. Problem in the bad placement of biscuits which I know aren't needed. They revealed themselves after sawing out the body. I've tried masking off the top and back to paint the edges a solid color, but can't get tape to stick to the rounded edges. Looking for ideas/inspiration on how to fix. Thanks for any help or ideas.
