Dielectric fluid is pretty harmless, but I will probably use kerosene for the dielectric. I think the fiberglass will hold up to that.Just to be on the safe side I'd use epoxy resin rather than the polyester. My boat from the 60's has fibreglass fuel tanks, an testament to fibreglass.

Yes, I am pretty much back to normal (whatever that is). The infection is gone and my incision on my spine closed up completely about a week ago. The only problem or danger right now is the high risk of a major stroke, but I am not letting that hold me back.GREAT TO KNOW ALL THE PRAYER'S WORKED, Your prior memo did not sound very promising, looking enthusiastically to your current project.
