When i see them i either leave them alone. esp. if its my bow for hunting. With truoil and a bow going to someone i have had good results softly scraping the area with scraper. sand the area.120,150,220.320,550. i then use fine steel wool to help fade the borders of the area you fixed so it blends better. I then use a small tip of cloth to hit just that area you resanded. i do the amount of finish you have put on already. i do lightly sand inbetween coats and tact cloth. i then continue to apply coats over the whole limb.
