Here is a youtube video I made on the Lionel GG1 zinc rot problem and the current fix. I posted this to help steer people to the OGR discussions about this and Harry Henning's current fix. I remember when I was trying to get replacement parts, and there were none. I thought this is the end for that engine, and it became a paper weight. Well now that there is a fix, I want to put some help out there. Link on youtube to help locations. Anyway here it is, ENJOY.
