Hi fishclan,
First of all, if your hard
paint is is still good, you wont have to haul. Hard
paint releases it''s copper without the
paint wearing away-you can have all
paint but no copper! The
paint can then be sanded ''til the cows come home but it won''t do any good, the copper is gone. So then, you will have to haul to re-paint.
With an ablative
paint, the
paint wears away as the copper is released- when the
paint is gone, the copper is gone.
With a hard
paint, each time you apply, you have to sand off the old
paint or it will build up. If you don''t sand, sooner or later you''ll have to strip the bottom because there''s just to much build up.
Alot of sailers use hard
paint because it''s cheaper, but when you have to pay someone to strip the bottom, there goes your savings. Some think it protects better but I think it''s a big pain. The savings aren''t worth the work.
If you can... haul your boat... strip it... and only use ablative
paint.
You could apply ablative over hard but I suggest you get rid of the hard.
At any rate... good luck.
