okay i found out its a sailing dinghy
, about 13 feet in length.
i would use something like brightsides paint
, cheap enough for that size boat. it should give a few years of looking decent. a quart should do the whole boat.
as for prep is pretty much the same as normal paint
, clean, scrub, clean some more. sand to remove loose paint
, fill and imperfections. then primer, sand primer till happy apply more primer, sand again then a couple of coats of top coat.
total cost for a boat that size is about 150, if you do it all your self.
if you want to go really nice, do all the prep work and bring the boat to a boat painting place, and have them spray it emron or awlgrip
, if lucky they will do it cheap when they are painting another boat, but you might have to wait till they are using a color you like
edit, do some reading here, they are lots of ways to do the work, spraying, roll and tip.
