I noticed QuickSteel has a maximum temp of 300 degrees F, and the two tube kind of JB Weld has a max temp of 600 degrees F. Anyone had any issues with QuickSteel on an engine block getting too hot?

I figure I'll be safe with the JBWeld, but someone might not notice that the putty version of JBWeld is also only good to 300 degrees like the quicksteel, you have to get the kind of JB Weld that comes in two tubes and you mix to be safe to 600 degrees.
