Robert D posted:Opened my Green/Solid Stripe JLC GG1 as I'm checking everything getting packed for a home move, and found zinc rot. Frames still hold together, though are bowed outward. The backs of the frames swelled to the point where they touch and bind. My solution so far is to carefully dremel-sand off paint from the inside portions of each frame to reveal raw metal then cover these areas with epoxy. Won't keep outside portions from flaking off, but may keep the frames generally intact.
Sent an email off to Lionel; naturally have not received any response whatsoever.
Local model RR store warned me, too, to check my 21" Lionel passenger cars. Apparently the trucks on many of these as well as the zinc rectangular piece under the cars are potentially affected.
And when you do receive a reply from Lionel, they'll tell you there are no replacement parts available. *Ask me how I know*. 
Further, by all indications, there are absolutely NO replacement power truck side frames anywhere on this planet and there are no plans to produce any in the foreseeable future. So, if you have a GG-1 with "Zinc Pest" eating away at your "Powered Truck Side Frame with Pilot", it seems that you are just plain out of luck. 
BTW, the Lionel part number is: 610-8354-035. *I know because I have the same problem with my JLC GG-1*
