At the age of these boats most need to be wet sanded. Its very easy to do but takes LOTS of arm strokes which most of you guys are already good at! Clean first, then 3 diff sanding grits and soapy water. Thats it! One good waxing after that and its brand new again.28606_1427105848432_4318817_n.jpg28606_1427105648427_6720786_n.jpg31394_1429129179014_3655753_n.jpg
