Flex seal may be the last thing you think of when it comes to your jeep but why? Well I've used it to seal a leaky radiator hose, valve cover gasket, cracked oil pan, and leaky roof. It's been 2 months now on the radiator hose and oil pan without so much as a drop of coolant/ oil leaking out so give it a try.

 

It might be good for sealing a roof, but I'd get a new radiator hose and oil pan. I wouldn't trust spray can rubber to seal up engine oil and antifreeze that's hot and/or under pressure

 

I've used it in far worse conditions this stuff is risiculously strong for what it is

 

I'v sprayed myself a pair of pants.. they hold up to high pressure.

Sorry... no pics.

 

Hmm I've never thought of that its actually a damn good idea
