Thermostat Housing Leak

Good to read what others have done to solve their leaks. I tried what a lot of you have done. Two gaskets, used RTV, thick gaskets, thin gaskets, RTV only, chrome housing, billet housing, sanding intake and housing, almost thought about trying to weld the two together. There was one or twice that the leak stopped for two to three months and then would start again. Just tired of spending money and not solving the problem.
All the help that I got from all of the members of ForABodies Only gave me is appreciated, and I thank everyone for their input. This is a great site to come to with a problem and have so many respond with what they have done to fix a like problem. There is a wealth of knowledge here that everyone is willing to share. Thanks again for all of you helping me out.
By the way, no leaks!!
