Cabin top repair

Originally the interior deck beams were bolted from the outside through the cabin top. The bolts were countersunk and the area filled and faired. There has been some cracking around these filled areas where the original plugs were filled.
Fix has been to grind out a depression above each bolt and then wet out with epoxy, cut a small 6 oz fiberglass cloth patch and carefully tamp it down and then fill with epoxy. This picture shows the bolt areas.
The boat is covered by a tarp that covers a "tent" frame made from thinwall conduit.
It has held up surprisingly well considering the pretty severe storms that we had this last winter.
