Hi,<br /><br />I'm about to but a displacmment hull boat that will be kept on a trailer for beach launching.<br />The current owner has been really straight about telling me that there is osmosis, but only several small blisters. It's been kept in a marina for the last couple years, hence the problem. <br />What would you do as the problem is no too bad and it'll be trailered?Any advice please?
