I got the most incredible item in my Christmas stocking (I was good most of the year). Rustoleum, which we have all respected as a rust inhibitor, has now put out a product that simulates rust on iron or steel. It’s a two part process and everything you need is included in this little kit. Can you  believe it? Rustoleum creating simulated rust!!! I’ll never buy their products again. Incidentally, their fake rust can easily be seen as it is a uniform brown color, much the same as some of the “rusted” items coming from the Orient.  To avoid problems, deal with someone you trust. I will be glad to look at your items to help identify their validity, free of charge.   Incidentally, I have found several J. Chein toys from the thirties and forties. Not cheap, but well worthwhile.  Stop by.
