dont get me wrong, i understand the need for a smooth hull, and 1200 sanding before everyrace, yeah if your in contention for world champs maybe. and i also know that all the 0.1%'s all add up, what i am saying is make sure you have all your 5%'s out of the way first. and good luck to anyone who wants to put the effort in to polishing hulls, ill drop my boat off to your place and you can practice on mine first. if its easier you can do my boat at my place, there is beer in the fridge in the " man cave", help yourself!!!!
