This is really good advice, I was just about to mention it. I take it one step further. After I give it a few whacks with a hammer I quick sand them smooth. I've set up a small 6"x9" piece of glass that I've tapped a piece of 600 grit w/d paper too. I just press the flattened wash down with my finger and give it a go. This gives you a very nice smooth washer/spacer in a matter of seconds.
