Removing Goo from Sail Numbers
Mark,
Once upon a time when I worked in a sail loft we use to sprinkle baby powder over the “goo”. We then would use a very dull like knife and scrap over the “goo” area. This would pull the goo out of the sail. It worked quite well. Keep in mind this was in the 70’s, but it still make be applicable today.
Good luck,
Brian
