[C320-list] Water lift Muffler

[amshd2 at aol.com]

I have used JB Weld in the past never thought about using it here but now considering it.  Does anyone know for sure how hot the muffler box gets.  Does it get up to $212 Deg F. 

After I read some of the emails about using JB Weld vs West System I gave West Tec Support a call. They said I  should be OK to over 200 deg F if I add Glass and the 404 filler.  I was thinking that since my eng operating temp is around `175 I thought I might be OK.

Bruce which JB Weld product did you use ??  I went on line to JB Weld saw lots of differetnt products.

Wonder if I can use JB Weld in the crack and cover with West and Glass.

I would rather go with over kill than have to do this again anytime soon.

Thanks Again

Tony

Bruce,
Brings up a good point.  West System Epoxies will soften with heat even
after well cured.  Most parts of the water lift muffler should never get
over 212 Deg F.  However, GB Weld is higher temperature and should not
soften with these temperatures.

West System is great stuff, I'm a big fan. However if or when I would make a
repair such as this (water, high temperatures) I'd use JB Weld (big fan of
that too), I only say that because I glued a broken hot tub water impeller
back together thinking "what the heck, it's worth a try", it worked for
years and as far as I know it's still together (We've sinced moved). But
West system good too, just a thought...

Tony,
I would recommend that you add milled fibers to the West Systems and clean
the area well with acetone after you are sure it is 100% dry.
Good luck!

work better than the west system please let me know.
