This curupay board didn't show these dark streaks until the sanding process, which was rather unusual.
Same board placed on a hard maple table.
No finish yet. After two full days of being exposed to direct sunlight, UV rays have done their job.
Finished with lacquer and showing off an exquisite maroon color
6 Months later with a lacquer finish and the wood is holding strong with a deep red color and all around stunning look
