Hi All... Sorry for all the questions lately, but I'm new to all this boating stuff.
I'm tryin to get my aluminum "Hardin Marine" exhaust logs to seal. I have the thick (.043) copper gaskets for it, but it's still not sealing. Is there any kind of sealent that can be put on the gaskets to help it seal? The old gaskets (non-copper) had some kind of black sealer on them & it seemed to work, because it wasn't leaking before I took them off. Also, can these logs be re-surfaced or something at a machine shop? Thanks again everyone for helping me out. It's really appreciated. Thank you...JT2Fast4u
