Since you are going to apply a finish, does it make sense to sand your piece to a high grit? Let’s see what happens to the resulting chatoyance. 5 couples of samples were sanded to 240-grit; then one sample from each couple was sanded up to 10’000-grit. Then each sample was coated with “Medium” shellac (2 parts in 13 parts of Alcohol). Table below summarizes the results expressed as chatoyance [PZC] increase from the 240-grit sanded condition to the shellac coated (4 coats) condition:
These results show that sanding to 10’000-grit provided an average benefit of over 4 PZC on the finished product.
Pictures below show a visual comparison of the results:
