the hull surface.
2. Sand the scratches and a 1-inch circum-
ference around them with 80 grit sand-
paper (either wet or dry).
3. Clean the entire area with acetone and
let it completely dry.
4. Mix gel-coat and gel-coat thickener to
form a putty, and then add the catalyst

the area with 80 ~ 400 grit sandpaper
