JoeKamel,
You are probably right... my method still uses the RTV as an adheasive, but the difference is that I let it "skin" by not torquing down the parts... Jaydee does. After mine "skins" and I torque it down, it's still in the wet adheasive stage in between the two "skins".
I'm not quibbling (at least not trying to) ... just giving my experience... and learning from others in the process.
Pureh20,
Probably nothing... however most epoxies are more rigid and will not allow for any flexing before breaking a seal. Not that these parts flex much, but that is the difference.
