I picked up a few 3*3 and 4*4 blocks of wood sold as turning blanks. I will use them to make some bandsaw boxes. The end grain on the blanks are all coated with a wax-like substance in consistency. One block is covered all 6 sides. Some are transparent clear coatings, some are colored and opaque.
Should I just mill this coating off, or hand scrape first, or use a solvent,...
Thanks,
