You have too much paste on there. I’d CAREFULLY scrape a lot of it off the strop and save in in a pill bottle or something.
Despite the directions, one inch is too much. A dab spread between the two paddles would be a better amount.
My strops are leather, and my compounds are paste, so I’m not able to answer much about balsa and sprays. But in general, it may be best to start with smaller amounts and add more if needed. You don’t want paste on your blade as that is basically wasting it.There is a section on stropping that may be a worthwhile read for you.
