I was curious,

I like my hulls to look perfect and I know it's always best to start clean from what I have read, but I've never done hull painting or sanding on one. So here goes; can a MiniCat hull be painted over with more clear coat of Krylon Clear Gloss or would that mess it up somehow? I would dread trying to sand it down and paint it all over again and have to clear coat it for some scratches. Or Can it be painted over with Krylon Flat White and then Krylon clear Gloss or does it still need to be sanded down?

Thank you kindly.
