8.5. Sand New Construction Only
Note: For new construction where the transom laminate has not been modified or repaired, follow this section. For old construction where the transom laminate has been modified, repaired, painted or otherwise compromised, skip to Section 8.6.
Sand down the gel coat with 60 grit sandpaper to remove the gloss surface. You may use a Dual Action Sander (DA), but you must be extremely careful not to remove excess material.
Note: It is important not to change the shape of the transom and to stay within the perimeter of the Transom Plate.
