That all depends on how reversible you need the new material to be. Some use silicone RTV caulking, which is not greatly affected by heat and is not easy to dig out if you need to. Others have used driveway crack filler that comes in tubes for a caulking gun. This tar-like stuff is closer to the appearance of the original but some brands of it take days to set up well, and if you are using it on a part that generates heat, may well have a lower melting point than the original tar.<BR>Usually I just remelt the tar that I poured out of the part and go with that. There may not be as much left as there was before, but it will be enough to secure the part back into the can.<BR>And some choose not to pot at all, but to rig up some mechanical method of supporting the part inside the can.<P>------------------<BR>Dennis
