What kind of sealer did you shoot? High enough solids and you're good to go. Whatever it was it can't be what Gibson been using lately as the grain on a lot of their stuff telegraphs clearly through the finish
On my EBO, none. On the JAEbirds, Mohawk high solids sanding sealer cut 50% with lac thinner. about 8 oz per body.
Gotta get on my soapbox again. Genuine mahogany, Swietenia mahagoni, is to African 'mahogany' as white oak is to red. They are completely different in cell structure- don't try to make a barrel out of red oak, it will leak. Ditto real Stickley furniture, white oak only.
If you've worked with the various woods sold as mahogany the difference is readily apparent. Swietania works the same in both grain directions and is a joy to machine,with both hand tools and power. No nasty, 'Philippine Mahogany' (luan) splinters or porous endgrain. Prepped correctly, sealer and top coats are all you need.
As far as I know Gibson does NOT use Swietenia mahagoni, except possibly on it's CS stuff Hasn't for decades, someone correct me if I'm wrong. I'm currently paying upwards of $11 b.f. for rough 8/4.
