Great product for use in High Temperatures
No problems found with the product. You must blend well for long time success.
The temperature resistance has show to be great........used on aluminium marine engine cylinder head.

Depends on application - not suitable for motorcycle exhaust systems
2 stars is quite harsh as it depends on the application with this product. I purchased to try and repair a leak in motorcycle header pipes. It’s easy to use, mould and apply and appears to set very strong but it broke away after a few minutes riding, the heat and pressure from header pipes was too much. Might be different in a car manifold or on other applications but this is definitely not suitable for motorcycle down pipes/head pipes. Read full review

JB Weld putty
Absolutely brilliant. Heat resistant mouldable, sanded, drilled, everything I needed. Would highly recommend this item.

Recommendable product - keep some in your toolbox !
I needed a quick fix on a cracked exhaust manifold. I doubted its capabilities after reading through what it claimed to do. However I was wrong - easy mix of the putty and straight on after a bit of wire brushing. I left it over night and the following day it had formed a gas tight seal that will certainly last until a get a chance to replace the manifold properly. Read full review

Catalyst converter repair
Put this paste according to instructions on the crack on catalysts converter. After 2 days drive found the crack appear again. Best to weld than using this product.

Only time will tell?
Can only rate ok, as it is too early to know whether the repair has been successful.
So far so good. Unfortunately review requests come far too early to give a meaningful response.
