Hi,

thanks to Peter and all posters, the meaning of RTV is now
clear to me. Did4nt ever thought to uses something like that in
a model-railroad-loco. I tink Larry G. Nelson just liked to
share his experiences he made using this kind of glue next to
the brushes of a motor suggesting to avoid the usage of RTV in
this case.

Kind regards
