the auto world transformer did well powering 2 lanes, and I made "jumper cables" and used 3 power feed tracks in paralell to the controller/transformer. it's the inter track connections that kill ya.
I also use this stuff to prevent rust/oxidation and improve the connections
I had the track on the shop floor for a week one thanksgiving and never had to clean the track
use it on the end connectors, too. I have used a dab on 400 wet/dry to clean up bad spots, clean with alcohol, apply a dot
