Yes I did Tom, and I love the hell out of that stuff. IDK if you will be faster. I'm already somewhere over 310 RWHP and 303 RWTQ. I got my valve covers sanded today, but I'm going to do some more tonight and tomorrow to make them perfect. I used wet dry sand paper and wet sanded them with 400, 600 and 2000 grit sand paper. Here's where I stand right now.
