Exhaust Leaks, Paste?

[Omer F. Khan]

In most auto parts stores you can find Hi-Temp Copper RTV which I have 
used many times on exhaust joints.  I have even used it without a gasket 
before and it will hold a long time.  Of course, you should use a gasket 
and just apply it to both sides of the gasket. 

If you have a hole in a muffler or a leak that is not a joint then you 
can find some putty stuff which you just work a bit like play-dough and 
apply it to the hole.  I haven't tried this stuff but some friends have 
used it for a quick fix.
