http://www.ebay.co.uk/itm/QUIKSTEEL-THERMOSTEEL-HIGH-TEMP-METAL-REPAIR-WELD-GREAT-STRENGTH-/121278008494.

Would it be ok to give it a try on exhaust manifold crack? I got used manifold last year from an OOF member, in good  condition, but it lasted for only a few months. Welding it again, as the previous one was, doesn't seem to fix a problem for a long time, esp. with all the work included to take it off.
Thanks, Stan

I've used other Quicksteel/Chemical Metal type epoxys in the past, including a repair on the sump of a TD, and its worked well. Not sure you would get it to take on an exhaust manifold, but never used the high temp stuff you linked to.

It has 2 choices, though shop around, as Halfords sell the normal (non high temp) for around a fiver, and they aren't exactly cheap!

Thanks TB, I'll give it a try anyway, can't  go worse than it allready is.

Perhaps you would like to try this product and put together a report/maintenance guide for OOF? If it works it would certainly be a useful tool in our armoury to help keeping our beloved cars going economically!

It would be hopeless on an exhaust (as they rust from inside), but *may* work on the manifold.

I've tried this stuff and others on my 4 pot manifold and in my case all they've done is form a 'scab' and lifted off before the day was out
Good luck with yours though

Withstands temperatures to 2400 degrees Fahrenheit   

how long ?

if thats true Nasa would have used it instead of expensive ceramic blocks

Its too heavy

I don't know if it is still being manufactured,. but ages ago I used Gun-Gum, both in bandage and paste form. The bandage you applied wet/damp, if I recall, and wired it on all around the repair, which helps with the "scab" problem that PhilRich mentioned.
As a belt-and-braces approach, I used to apply some paste over the assembly afterwards. Seemed to last well and the MOT man was happy!

This is for a manifold, so bandages are out

Its too heavy

the ad doesnt mention about its atomic weight 

(its a liquid as far as I see)

If its like the non high temp stuff, is weighs about the same as steel once cured.

For TB and Cem - the WEIGHT of money spent into repair is most important  I could buy a new manifold, which is the best solution, but it costs 1/3 of miggy value and that just isn't acceptable. Welding it also doesn't help for a long time

Indeed, given the low cost, there is nothing to lose .  I doubt it will work very well, but won't know until somebody tries it

Epoxys can fix anything , even an FJ1100 carb
