My boat was freshly painted with Micron CSC and I had to pull it out after only 3 months due to hurricanes (2). I power-sprayed it at a car wash, to remove scum and slime, then stored it. 5 months later it is time to put it back in the water. The bottom is 100% free o f slime and scum and the paint is perfect. Can I power-spray it again and them paint two coats of CSC over bottom without sanding? Or should I just power wash lightly again and put it in the water?
