welding with Durafix!!</DIV>
<DIV><BR></DIV>I've had similar experience. There's a knack to using it
that I haven't picked up. My joints are functional but ugly. Often there
is some porosity. I have used it on 4-stroke exhaust to repair pipes and
repair a slimline Pitt's muffler on a YS140. 4-stroke exhaust temps are
no problem. <BR><BR>One problem I have using it is getting and keeping
the temperature right, too cold it doesn't flow (probably why I get porosity),
not very much hotter and the aluminum gets soft. One thing I haven't
tried that might be helpful is to use one of those non-contact temperature
guns. It would have to go to 800 F or better.<BR><BR>Ed<BR><BR><B><I>Bob

<DIV>I've used it on a mousse can muffler on a two stroke and it is still
holding up. Not sure about a four-stroke exhaust, which can get a lot
hotter, but I suspect it would do ok.</DIV>
