Anyone have experience using 3-in-1 oil as a lubricant for model railroad motive power and rolling stock? One of my tenders has developed a nasty screech. I don't have any lubricant specifically marketed for model rairlroading, but I do have a bottle of 3-in-1 in the garage. The label makes no mention of any harm to plastics or painted finishes. I'd hate to learn this the hard way. Thanks.
