High Temperature epoxy/adhesive
I have a small gap in between my wastegate flange and wastegate, so obviously without anything there it leaks when the gate opens..
Anyone know of any high heat epoxy/putty/adhesive that would withstand the temperatures? I have tried a few things(JB Weld/high heat sealant/copper gasket maker goop), but neither worked for very long.. JB weld lost its bond, the sealant stuff bubbled up, and the copper stuff eventually came off too..
I found this stuff called Hi Temp Lab Metal but wanted to ask if anyone on here had used anything similar to what I am looking for before I spent the $40 on it..
If I can't find anything I guess I will have to get it brazed, but I would rather do something else..

Re: High Temperature epoxy/adhesive
what kind of wastegate. is this the flange before the wastegate or after?
if its a tial, there is a round ring gasket machined from aluminum. it is the sealing section of the wastegate.

No, there is a gasket, its just the flange is for a 38mm tial/rotomaster/delta WG, I made that gasket out of aluminam tin foil/copper spray 
But the thing is the wastegate I have is some WG that comes with ford 5.0l turbo kits, its a huge WG, 44mm, but has the same bolt pattern, but the hole in the WG comes over the edge of the flange 1mm on each side or so.. I got it for cheap is the reason I got the WG and its nice and I don't think I will need a bigger one anytime soon ahahaha.. the flange is before the wastegate, turbo manifold side.
Here is a pic of the WG:

I already had to make a flange for the other side, don't feel like doing it again, plus the flange on there is a cast stainless flange, I would rather not butcher my manifold if I could get around it, which is why I asked this in the first place.
