I was not able to make the club meeting last weekend but luckily for me it was all captured on video thanks to @Mike T ! Our esteemed George Kraus reviewed his extensive Norton tool collection. It's great having such knowledgable local resources like we do here. Then we had Denny Torgeson talk about using paint clay to remove contaminants from an original tank. Each little particle adds to the dullness so you can get a much better appearance the cleaner the surface is.
