Well the paint you use depends on where you take your boat. Ocean? or just Lakes? Is the boat currently gel coated or automotive paint. If automotive paint is it single stage or two stage? If you go with automotive paint do you want to use single stage or two stage? Are you going to spray it in a booth? Gel coat isn't very hard to spray and it is fairly cheap. You just can't spray it with a gravity feed gun. And you can spray it outside or in a garage. You don't need a booth. Also gel is more durable and is easily colorsanded and buffed to perfection if you scratch it. The most expensive gel you can buy is a custom color and that is only about $75 per gallon. Just some food for thought. :idea:
