Aluminum TIG welding wanted

[Goat Blower]

I did try JBWeld as that's what's on there now, but it leaks and is starting to fall apart. I'll be selling this car and want to know that this repair will last the life of the car, so JBWeld just isn't a viable option, it was just so I could drive it around for a while. I'm bringing it to John this weekend for him to work his magic. Thanks for the tips.
