I am going to give my old boat a paint job since it needs and give it a new fresh new look. I have read different articles about how to get the boat ready for painting and painting it. My question is, how much paint do I need? I own a old 1972 16ft Terry Bass Boat. My boat's bottom is white, and top part is green, and I'm still thinking about if I want to keep it that color scheme or change it. But I was trying to figure out if I keep it the same how much paint would I need for the top and then how much for the bottom? Then my second question is how is the best way to paint the area where the guide rails are? My only guess right now is when I take the boat out, take the guide rails off and load the boat without them, paint (when boat is dry, paint entire boat), then next trip put the guide rails back on.
