8.7 Aluminum Hulls

For aluminum hulls, use 80 grit sandpaper, a grinder, wire brush or a Dual Action sander to scuff the entire mounting surface to remove all coatings and oxidation until the Seakeeper Ride Controller area is a rough surface with no impurities for the MMA to adhere to. For aluminum hulls be sure to follow MMA manufacturers recommendations for surface preparation and application of adhesive.
