That's "Honduran" mahogany or so I was told when sold. It is definitely not sapelle.

I used Waterlox Original Sealer Finish (Original formulation).

Are you building a film? OSF tends to settle from gloss at application to semi-gloss at cure.

Also, as I know you know, if you don't build film with this, it will be satin. You could seal with it, high grit sand, then final polishing coat.
