Re: My first boat restoration-'71 Starbuck
I cant help you with the sanding question but (I think I speak for everyone on this) I would love to see some pictures of your boat! Pictures make all the difference in giving advice and providing some color to spruce-up the threads!

Also, I have read several posts on sanding old paint off fiberglass so whenever you have some spare time, search through some posts and see how other people have done it.
Good Luck on your build!
