Fibreglass patch over shaft log

Well, the shaft log hose on the '68 had ballooned out and was in need of replacement. The back half of the hose was glassed over by the factory. I guess they figured the hose would outlast the boat. So, I began by using my Dremel to cut out a rectangle on the top of the shaft log. The cut turned out to be about 3" longer than necessary. So, I now have about 3" of exposed brass shaft log almost all the way down to the bilge floor. I would like to glass over the exposed shaft log. The thickness of the removed glass is about 1/4". How many layers of glass will I need to lay on to build up to 1/4"? Is the type of glass weave important to this kind of patch? Should I use epoxy or polyester resin? Should I keep applying the glass until the thickness is reached or should I let dry and sand between each layer? Anyone?

Does the bilge have gel coat over glass like the hull?

I think there's something fishy here. Seems to me that the factory would have put the running gear in well after the glass had set. Maybe it was a repair done later?

I could also be way off base.

Thanks for the replies. This will get me started. Where should I order, online, small quantities of matt and roving fiber glass?
I remember reading on the forum a few years ago, that CC covered the shaft log hoses on early CCs. Others have experienced this. Who knows what the factory was thinking. The aft hose clamp was completely covered with glass. Isn't that something? FYI, I ordered a new shaft log hose from skdim. I cut it from 6" to 4" (the length of the original) before I figured out that the original hose is 1-1/2" and the replacement hose from skdim is 1-3/4".

Cool, I learned something today; can I go to bed now?    

The hulls must have been drilled after they were popped out of the mold.
