Will this dodgy In-manifold fix work ?

[Ext User(james)]

I have another manifold i want to try fitting on my car, just to see
how it goes. It's been sitting around for ages and has a bit of
corrosion in it.
If you look at this pic

(35k) you will see what i mean on the water port, it's like it on all
4 water ports.

Now what i have done is fix it up with an epoxy like stuff, stuff
called quiksteel which comes in a sort of putty, basically has the
exact same specs as JB-weld. So i used that and formed the port back
to a nice stock rectangular shape and filled it flat with the rest of
the manifold. Any chance this will hold once it's on the car?

I would've used Devcon -- which AFAIK is still the industry standard
in epoxy putties for your type of application..

If what you've used is as good as Devcon it shouldn't give any
problems provided you sandblasted it first. If you didn't it isn't
likely to adhere well enough to survive for long.

Bugger. I didn't sand blast it. I sanded back though with sandpaper
and cleaned it up with something, might have been acetone. I will
look up that devecon stuff to see how it compares to what i used.

Not sure which devcon product to look at as there is hundreds, but the
stuff i used is basically identical to the devcon Plastic Steel® Putty

That's one I keep and it's what I'd use for a cast iron manifold. Also
got another one for aluminium.

Problem with Devcon for DIYers is that it only comes in industrial
quantities, which makes it awfully expensive if you only need a few
grams. If you keep it in the fridge it'll last for years though (same
goes for bog, super glue, etc).

Like all similar products it's success is highly dependant on surface
preparation and cleanliness. The Devcon directions are (in part)....

"....abrasive blast to visual surface cleanliness Class 503 to
Australian Standard AS1627:9 2002 with a profile of 75 microns using
clean 10-40 mesh grit. If abrasive blasting is not possible, roughen
the surface with a grinding wheel."

If you happen to have access to a Snap-On sandblasting cabinet with
vacuum dust extractor, as I currently do, then you're really cooking
with gas. :))

Sandpaper is OK for very small areas -- otherwise you'll wear your
fingers out before it's clean.

I also use a carbide burr in a die grinder for some applications.

Some of the Devcon products are produced in toothpaste tube size packs, but
I don't know of the availability in Australia. I bought a 6.5 oz/184 gm
pack of Devcon "F" Special Epoxy in the USA several years ago. I have also
seen similar sized packs of other Devcon products at a local flea market in
the last 12 months.
