very little fouling in the med,but if you can get it i would continue with the pettit or equivalent.
if you can find "tamarine" in
turkey this is a tbt based

what ever you use,you need to be careful about over painting,pettit is a co-polymer ablative paint,so stuff from jotun,or hempel wont stick to it.
tamarine,international,etc will
