I was at a big car show that I won't mention some time ago and some young vendors had a Kirkham on display that someone loaned them to display their new filing / sanding and polishing techniques. I went back there 3 times during the show to measure their progress.
They had it sooo screwed up I couldn't even look anymore!
I want to think they had a plan and technique, but trying to do that in front of thousands of people wasn't a good plan. Like making sausage...
