I must admit when I heard Nick say "no shellac on the cold plugs" I was shocked. I mean, I don't goop them all to hell, but I run a film of RTV around them with my finger. Never had one leak yet.
I miss stuff sometimes, everyone makes mistakes if you do it long enough, but there is wayyyyyyy more than a few mistakes in that build. I just seriously dont know why Nick's garage would even publish that video...kinda strange
