My question is about vents. In an old boat I have I spend considerable time installing grills/vents in all areas trying to keep lots of air circulating. Admittedly this is not metal, normally fiberglass hatches and areas inside the structure. So now I am looking at rust issues inside the cowls and doors and wondering why we don't cut grills and vents into door posts and door frames to allow air circulation. Some of my problems are wet areas and sound deadening that just can't dry out. I live in Vancouver BC where rain is prevalent. Hoping to hear some comments about allowing air instead of sealing everything up. Thanks. Doug
