One of our staff, Johnny, powder coated his 18' Sea Nymph. According to lab results, a powder coat finish over sandblast and using an epoxy primer has a significant performance upgrade over Zolatone.
He chose an orange-yellow sparkle exterior and a dark gray hammertone inside. The finish was done by RMC Powder Coating in Seattle.http://aluminumalloyboats.com/posting.php?mode=post&f=3#
