glassing over removed thru hull. what glass to use?
I have removed a 2 inch diameter thru hull fitting in my fiberglass sailboat. The hole is underwater and the hull is ½ inch thick at that point.
My main question is regarding the type of glass I should use in making this patch. I will be using West System epoxy.
I have seen much info about doing such a repair, but what fabric exactly I should use remains a question. I would like to make the repair as strong as possible.
Some say use 1708. Some say 1708 with mat, some say 1708 without the mat. Some say 12 oz cloth would work.
My guess is that most any fabric would work, but I have to choose one. I do have confusion over chopped strand mat. I know there is the stitched type that would be compatible with epoxy. But is the CSM necessary?
If I had to do it right now, I would use 1708 with no mat….
I feel confident in my ability to lay up the glass from both the inside and the outside. The inside does not have as much room for tapering the patch, but I can still do some lay up.
So what fabric should I use?? Please, thank you!!
