[T3] Best Practices for Muffler Preservation

[Sean Bartnik]

Hello all,
I've been out of town so not much time spent with the Eggcrate lately. Now I'm back and looking at upcoming work...

I think I mentioned earlier that I've got a little pinhole exhaust leak at the muffler on the left side at the seam where the lower pipe enters the main muffler chamber. I tried a quick fix with some muffler putty but that hasn't really accomplished anything (unless I have more than one leak and haven't discovered the other one yet). 

I'm considering removing the muffler again and having it welded up properly but if I do that, then I also want to do something to preserve it properly for regular use. 

The muffler is currently in good shape, not rusty but it has only the factory coating on it which I know isn't going to last long in real use. 

I just want to get some feedback from the experts here as to what is the best way to go for long-term preservation. The options I'm aware of so far are: 

1) Prep & very-high-temp paint 
2) Prep & ceramic coat 
3) Prep & very-high-temp powdercoat (if such a thing exists) 

I'm also thinking that whatever I do to the muffler I should probably do to the heat exchangers at the same time. Any thoughts on the best route to take here? 

Thanks,
-Sean
