The Permatex thread sealer should work. I have used Permatex gasket sealant which is a sticky purple liquid. It stays flexible and cleans up easy w/ ethanol. Use it so often I keep a can on my work table.
Yes, the Permatex worked very well, no more leaking, I am very happy with the product. I am happy I found the leak problem in the new Doug Dutra book. I am learning more than I expected by reading through his chapters.
