Interesting finish with Kustom Grit, new to me. Do you put anything over it?
The Kustom Grit is a 50,000 grit Food Grade polishing paste. I sanded the board down to 320G then using my Bosch Polisher on its slowest speed with the yellow pad & the paste start working it. The finish is so good and only requires a very mild lukewarm wash to clean it after use. 
The developer and owner of Kustom Creations is in Brisbane, Queensland; always helpful if you have any questions. 

Life’s Good, Enjoy Each New Day’s Blessings
