to fix undercar leaks...oil and trans fluid minor leaks is it ok/work good to used copper gasket glue.....or if not what product should i use...and where should i apply it......oil pan outline..and trans front and back cover?????
I've used gasket sealers in the past with good results. It also helps hold the gasket in place on the pan surface while you put it back up. However, I haven't used that stuff with silicone type gaskets. Some gaskets specify an RTV type sealant, too. Just check with the gasket manufacturer for their suggested sealant.
