There are bead tear-out areas are around the nose and along the stringer of my EPS shape. I don't want to keep removing foam and take a chance at screwing it up. What is the secret to sanding them out if I should do that?
To fill in any marks we spackle the entire board with light weight white spackle. Then you can take screen and smooth out all the spackle once it has dried. This is purely an aesthetic step to give the board a perfect look to the finish.
