Thanks Al,
I was thinking of an application like holding seated runners in the machined
manifold.  Or possibly joining tubing together.  The ability to contour and
smooth this product would seem suited here where air flow is an issue.  But
I don't know if it would stand up to all the rigors (vibration, heat, etc.)
Just throwing it out there since JB Weld is smoothing the ports on several
intakes out there.

On another note, has anyone contemplated using the two part puttys in areas
like intake manifold construction.  I saw some in HD that claims good for
temps up to 450.  I'm hesitant, but this stuff seems to be a cousin to JB
Weld.
Bryan  JB weld ( and similar) is wonderful stuff that adheres to almost anything,
and is amazingly strong.  So if need things to hold together and make a good
seal - great.  But if you need real strength, anything that just adheres to
the surface is not going to be as strong as a good weld.  So consider your
application, and what it has to do, and then decide.

FWIW,

Al G
