Fiberglass hatch rebuilding

[Capt. Mac Creech]

I have an older fiberglass deck that came on boat. Hatches have started to have a little cushion to them Took the worst one that actually had a sway in it and as expected the wood material inside was soft. I have removed all of rotted wood and would like to know the best way to fix the cover. I'm sure I'll have to end up doing them all. At first I was going to use mat and resin and build up untill flush. Do any of ya'll have a better way?
Thanks, Mac

Mac,

Dig out all of the wood cores and replace with Coosa/Pensky Board. Preferably using epoxy and fillers, but polyester will also work for hatch covers. Place the hatch covers top face down and weight them heavily when replacing the cores so that the covers come out perfectly flat. A final layup of chopped strand mat over the back will seal out the core.

Thanks Capt. didn't think about doing it upside down. Will make it a lot easier. Hope everything is going well. Port Eads is supposed to be back open soon.
Thanks, Mac
