I have two balsa strops. I have green paste and white paste, I also have red powder (.1 micron) and green powder (.3 micron). So with two strops, which of these should I put on the strops? And should I use these strops before going to the leather? I am brand spanking new to balsa stropping. Also, I've read you use the white lapping paste after the green paste? I thought the green always comes first?
