Been there, done that Kathy.
Most all my boats have required serious rescue to get em looking good.
If the "hazy finish is a consistent color I wouldscrub off all the old
oxidation to a consistent dull color using a non abrasive cleaner with
a product called TLC with a blue #3, scrubby pad. Then topcoat with a
polymer called Poli - Glo and it'll shine like new..This will not
restore color but if all the same tone after scrubbed down will restore
a maintence free shine.. tom

Hi...we have purchased a '73 AmericanDaysailor 16 - Fiberglass. The
boat is great, but the blue hull is covered with a whiteish haze. What
would anyone suggest to get her looking a little better? We do not
want to repaint. Thanks,

Kathy
