Thank you to everyone that took the time to respond. I understand the pros and cons to each approach.. I am talking about a fairly large area; approx. 3' high by the inside circumference of the boat , probably 40'. That is a lot of hand sanding, so I think I will try both approaches, starting with trayder's first up under the gunnel, so if I cut through the new gelcoat it will not be noticable and I could always reapply when it gets warm. For the tighter places where power sanding will not work the block and wet sand approach will apply. Thanks again. Rich
