Fiberglassing in hole in thick hull.

[zboss]

Hello,

I am moving two through hull's further up on our hull and when we take then out we will leave two holes. Our hull is about 1.75 inches thick layup at that location. They used both fiberglass chop and cloth.

Obviously, if I followed the directions from West Systems I would need to grind out a sloped area three feet across. That's insane!

I was thinking about epoxying in a plug the total thickness and then grinding down both sides so I only needed to grind an area about 6 to 8 inches in diameter.

Opinions?
