If the bottoms are the only problem, just redo the bottoms. I don't do anything cosmetic to the bottoms. Leave the repair raw.
What color is your boat? If it is white and you are refinishing white, that solves a lot of problems.
The hulls are a basic white. I have decided I want to get the boat out on the water as soon as possible. If I want to go further with total paint/gelcoat I will start in the winter. So here is what I think I should do immediately.
1) Brush gelcoat on skinned off stripes on very bottoms and dab some touch up on any deep gouges/chips in topsides.
2) Sand and feather edges of new gel coat. What grit and type of sander?
3)Wet sand hulls and seal with Vertglass. What grit sequence?
I appreciate everyones help in keeping me from getting carried away! <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" />
