Response from Hunter
I appreciate everyone's response to my questions. The answers were quite helpful. I called Hunter yesterday to ask about the fix they have listed on their web page. It was specifically for a bow deck separation problem. Apparently one person drove under a bridge and the act of the mast hitting the bridge pealed up the deck from the hull at the bow. Their fix strengthens this area.The engineer I spoke with looked at my picture and recommended that use a tool such as Dremel to cut into the crack area, only taking out the prior marine putty, but only going 1/4 to 1/2 inch deep. I was told to make sure I didn't cut into the fiberglass, but just the putty. Also, it was suggested that I go passed the end of the cracks just a bit to make sure that all of the separation would be dealt with. Once this was done, use a marine putty (I will probably use Marine Tex as I can get it locally) to fill the new cut. 5200 was not recommended due to its physical nature. I guess it is fairly runny in warm weather and I would probably not be able to keep it from running out of the grove. The putty should do the trick. He said that I may have to do a couple of layers of the putty since it will shrink as it cures. Once the putty is to my liking and cured, put a layer of gelcoat on, then replace my rub rail.I'd suggest calling Humter Marine prior to making any repair like this just to make sure this is appropriate for your situation. They were most helpful.I'll let you know if the plan does not go as expected. Thanks, Jimhttp://www.sailidaho.com
