any bare al. has to be primed with zinc chromate

primer. sand the old paint a bit and just roll

and tip a new coat on. I like the "petit" line

of paints, but there are lots of choices. some

can be over $100/gal. if you keep it in the water

and want anti-fouling bottom paint, make sure u

get one made for al., reg. bottom paint has copper

and will react to al.

good luck,

M.Y.
