sea hood core damage

(1/1)

jimma4191:
Hello,
    I replaced the dorades on my 33-2. In the process found that the core in the sea hood was not good. Cleaned out as much as I could. Has anyone replaced this core with a spray in polyurethane foam? Mostly worried about the expansion rate of that stuff I think. It could buckle the hood. Not sure I could get west system thick enough to hold vertically. Any thoughts or suggestions would be appreciated.   Thanks,  Jim

There is a foam that's used for around windows that does not expand as much.you can buy it at home depot. I believe it's Great Stuff for Windows.

This is how you apply fiberglass upside down.

Apply a thin coat of epoxy with fast hardener on the surface. No cloth yet. Wait for it to get sticky. Once it's sticky, really press the fiberglass cloth into the sticky epoxy. Wait 5-10 minutes. It will not fall now. Wet out the glass with fresh epoxy. Good luck.

Mike
