This is a bit off topic but I have learned more from this forum about using epoxy than any were else I figured I might get an answer here.
My problem is I have a fiberglass MC Scow sailboat and the hull is delaminating from the internal Keel. I want to inject thickened epoxy into the inside of the keel through approximately 1 to 1.5” holes and need to reach about 40” in. The plan is to tip it on its side and let gravity help it onto the gaps. I have west system fillable caulk tubes and will attach a long straw (orange drive way marker left from snow plow service) if I don’t get a better suggestion.
just got a WiFi borescope and figure that I might be able to tape it to the straw and see if the epoxy is covering. Probably will totally muck up the scope.
i don’t need a perfect or even pretty joint, it will be inside and Not visible, but need to cover a good portion it.
In the attached pictures the grey part is the keel with floorboards, and there are flanges around it which I have glued with West Systems Six10.
