So I have an orange cat and the paint is pretty faded. I'm getting it professionally painted by a friend and I'm in the process of getting it prepped. What are somethings i should do before i get it painted. How much sanding is required if im painting the boat white? What method do you use to sand it(hand sander?) And if i know of areas where there is a small leakage of water, what should i use as a filler for these spots. Any help is appreciated
