Marine Tex does not list a maximum temperature. I want to secure a loose fitting on an stainless oil pan and tack welding requires complete R&R (which I hope not to do at this point in the summer.

Marine Tex will do the job if it withstand 212 degrees, occasional spike of 230.
 
Jb weld is good to like 500 degrees or something. I used it on a cracked jeep manifold for a quick trail fix that ended up lasting forever. I would think it got up to at least 500 degrees. It is cheap and easy to find too.

From Marine-tex website

"How high of a temperature can Marine-Tex withstand?
Depends on pressure and conditions. Up to 250°F constant temperature in a dry environment, with spikes up to 300-325°F."

I looked up JB weld too. They claim 500 degrees for the origainal and 300 for the putty stick.
 
Hey Trim,

Is the original JB a base and catalyst mix? I only recall seeing it come out of a tube and just air set.

Is it as strong as they claim? ie, have you used it to hold things together successfully? Just curious here. :sifone:

PS thanks for looking up the Marine Tex, Guess I am lazy. :willy_nilly:

All of the JB weld I have ever seen is 2 part. It has 2 seperate tubes or there is the putty that comes in a stick that you mix together. As long as you rough up the surface it is some strong chit. I always keep a couple tubes of it in the jeep for trail fixes. Last year my buddy knocked the corner out of his transfer case on a rock and we put it back on with JB weld. It held fluid with only a minor leak and it stayed on, and it was a big piece, like 2"x4". He replaced the case but it is still together in his garage.
