As most of you old tracks had at home that could not use because they were touched, had used to clean polish, twenty things, but on returning to try to use them, they were badly again time, so the solution could be self-adhesive copper tape 
so estava one of those tracks 
clean with alcohol and he was so pege tape before reviewing a rag 
With the two-lane after passing a pressing cloth over the tape 
once I found them stuck a little shoe polish those who take the sponge and the track seemed new, just missing the corners and try to mount 
curves started hitting the inside of the fence and removed the small bumps that to tape the force curve with scissors, with the curve where the fucks, and reviewing the tape and was quite well 
motar It's only a track and see if funcioanba 
was nice the entire track tension and without any fault Hope you
helps Greetings
