Gotcha. Ok so in answer to your question about the epoxy where you already applied it on the sides, I'd simply suggest doing a little spot sanding along the edges of the coat where it meets the mahogany so there isn't a "lip" --- it will make it way easier to put coats on the back that appear to seamlessly blend into the sidewalls. Don't worry about witness lines where the back coat meets the side coat, as long as it is a smooth texture without dips or bumps, it should disappear after you put some clear on top. However, you may want to put some dewaxed shellac in between the epoxy and whatever clear you are going to use, so as not to run into any compatibility issues.

Don't do that! Epoxy is one of the very few things Shellac won't stick to.
