Refrigeration and plastic

by Mike
(Oakland)

I totally rebuilt the refrigerator in my sailboat. I re insulated the inside and relined the insulation with a thermoplastic vapor barrier and then fiber glassed it all in using a glass mat and polyester boaters resin with a tiny bit of white dye to make it look nice. It turned out great. Looks nice and keeps everything cold, but i have one disconcerting problem. It's about a year later and there is still a plastic smell in the fridge and I can taste plastic in my food too. It's horrible. What should i do? It shouldn't be out gassing for this long. Do i need to coat the inside with some kind of sealing paint or what? I am at a loss for what to do. Any help would be greatly appreciated.
