A recent article in Good Old Boat described the process and materials used in building a "one of a kind" water tank. It was just what I needed since I am redesigning and rebuilding the main cabin of my J40. Following their instructions and descriptions, I got the potable water epoxy used in the construction and have the project well along. Problem is, the dog (or the gremlins) ate my copy of the magazine before I bought the right kind of potable water safe caulking to seal the fittings and inspection ports. Can someone who still has a copy tell me what they recommend for that purpose? Alternately, if anyone knows what should be used for caulking the fittings that will not leach nasty chemicals into the drinking water, would you pass this information on? Any help would be greatly appreciated.
